I am using this code for datalist validation.
I am binding the image in datalist after that i am trying to give the caption to each image suppose there is 3 image is datalist then for the first image i am able to give but for the other one i am unable to.. i think there is some error in conditions help me in this. code is following..
if (DataList1.Items.Count == 0)
{
msgError.Text = "Please add images and captions for each image";
msgError.Focus();
}
else
AddCaption();
bool IsEmptyCaption = false;
Hashtable htble = (Hashtable)ViewState["imgIdCapHtbl"];
List<int> imgIds = (List<int>)ViewState["imgIds"];
if (htble != null && imgIds != null)
{
foreach (int id in imgIds)
{
if (htble[id] == "")
{
IsEmptyCaption = true;
break;
}
else
IsEmptyCaption = false;
}
}
else
IsEmptyCaption = true;
if (DataList1.Items.Count == 0)
{
msgError.Text = "Please add images";
msgError.Focus();
}
else if (IsEmptyCaption)
{
msgError.Text = "Please add captions for each image";
msgError.Focus();
}
else
{
Args[0] = "Section1";
Args[1] = "";
Args[2] = FindingId.ToString();
Args[3] = FindingIdIns.ToString();
AnotherHeading = false;
//AddCaption();
objGetBaseCase.UpdateImageCaptions((Hashtable)ViewState["imgIdCapHtbl"]);
if (AddFindingsViewerDetails != null)
AddFindingsViewerDetails(Args, e);
ClearImages();
PageContent pg = (PageContent)this.Parent.FindControl("PageContent");
if (pg != null)
pg.LoadWorkflowForCase();
if (Display != null)
Display(null, EventArgs.Empty);
}
if (DataList1.Items.Count == 0)
{
msgError.Text = "Please add images and captions for each image";
msgError.Focus();
}
else
AddCaption();
bool IsEmptyCaption = false;
Hashtable htble = (Hashtable)ViewState["imgIdCapHtbl"];
List<int> imgIds = (List<int>)ViewState["imgIds"];
if (htble != null && imgIds != null)
{
foreach (int id in imgIds)
{
if (htble[id] == "" || htble[id] == null) // New code implemented here
{
IsEmptyCaption = true;
break;
}
else
IsEmptyCaption = false;
}
}
else
IsEmptyCaption = true;
if (DataList1.Items.Count == 0)
{
msgError.Text = "Please add images";
msgError.Focus();
}

Now its working fine...

I managed to create a TreeView method for NodeMouseClick and CursorChanged events.
private void Node_Selection_Action(object sender, TreeNodeMouseClickEventArgs e)
{
// my action code here...
}
private void TvwPanel_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
{
Node_Selection_Action(sender, e);
}
However, I am getting an error on e parameter when I applied the method to the CursorChanged:
private void TvwPanel_CursorChanged(object sender, EventArgs e)
{
Node_Selection_Action(sender, e); //error on `e` here
}
I supposed this is due to the parameter EventArgs that is not compatible with my method parameter TreeNodeMouseClickEventArgs.
Is there any workaround that I could use to trigger the CursorChanged event with my method?

In the Node_Selection_Action method, the last if statement block:

{
Point ClickPoint = new Point(e.X, e.Y);
TreeNode ClickNode = TvwPanel.GetNodeAt(ClickPoint);
if (ClickNode == null) return;

Point ScreenPoint = TvwPanel.PointToScreen(ClickPoint);
// Convert from Screen coordinates to Form coordinates
Point FormPoint = this.PointToClient(ScreenPoint);
CmsPanel.Show(this, FormPoint);
}
is the only block of code that needs the TreeNodeMouseClickEventArgs properties. If you really need to pass this type of argument to the method then create one:
// Still no idea what is the relation, however...
private void TvwPanel_CursorChanged(object sender, EventArgs e)
{
var s = sender as TreeView;
var p = s.PointToClient(Cursor.Position);
var ht = s.HitTest(p);
if (ht.Node != null)
{
var args = new TreeNodeMouseClickEventArgs(ht.Node, MouseButtons, 1, p.X, p.Y);
Node_Selection_Action(s, args);
}
}
Unless I'm missing an access to the sender param in your code, you can omit it to simplify the method signature:
private void Node_Selection_Action(TreeNodeMouseClickEventArgs e) { }
Also, you can determine which mouse button is pressed anywhere in your code through the Control.MouseButtons property. The Control.MousePosition property gets the cursor's position in screen coordinates. So, maybe these two properties are all what you need.
Maybe the mentioned above last if block is in the wrong method and moving it into a new method or elsewhere in the context could be better.
Hope that helps.
I want to create filrer for 4 fields. But I get too many code.
I need filter when just one field choosen or a few (2,3 or 4) fields at the same time. How to create logic for it?
My ugly code:
void ViewSource_Filter(object sender, FilterEventArgs e)
{
if (e.Item is Event evnt)
{
bool selectedModel = filterEventsControl.ComboBoxModels.SelectedIndex != 0 && filterEventsControl.ComboBoxModels.SelectedItem != null;
bool selectedIp = filterEventsControl.ComboBoxIPs.SelectedIndex != 0 && filterEventsControl.ComboBoxIPs.SelectedItem != null;
bool selectedParameter = filterEventsControl.ComboBoxParameters.SelectedIndex != 0 && filterEventsControl.ComboBoxParameters.SelectedItem != null;
bool selectedStatus = filterEventsControl.ComboBoxStatus.SelectedIndex != 0 && filterEventsControl.ComboBoxStatus.SelectedItem != null;
if (selectedModel && !selectedIp && !selectedParameter && !selectedStatus)
{
var model = filterEventsControl.ComboBoxModels.SelectedItem.ToString();
if (evnt.DeviceName == model)
{
e.Accepted = true;
}
else
{
e.Accepted = false;
}
}
else if (selectedModel && selectedIp && !selectedParameter && !selectedStatus)
{
var model = filterEventsControl.ComboBoxModels.SelectedItem.ToString();
var ip = filterEventsControl.ComboBoxIPs.SelectedItem.ToString();
if (evnt.DeviceName == model && evnt.Ip == ip)
{
e.Accepted = true;
}
else
{
e.Accepted = false;
}
}
...
else
{
e.Accepted = true;
}
}
}
It can be something like this:
bool FilterByName(Event evnt)
{
var model = filterEventsControl.ComboBoxModels.SelectedItem?.ToString();
return evnt.DeviceName == model;
}
bool FilterByIp(Event evnt)
{
var ip = filterEventsControl.ComboBoxIPs.SelectedItem?.ToString();
return evnt.Ip == ip;
}
void ViewSource_Filter(object sender, FilterEventArgs e)
{
...
bool res = true;
if (selectedModel)
res = res && FilterByName();
if (selectedIp)
res = res && FilterByIp();
...
}
I want to know if a Word Document has page number in the Header/Footer using Interop.Word in C#.
I have gone this far
try
{
foreach (Section SectionObj in DocObj.Sections)
{
foreach (HeaderFooter HeaderObj in SectionObj.Footers)
{
if (HeaderObj.Exists && (HeaderObj.Shapes.Count > 0 || !(string.IsNullOrEmpty(HeaderObj.Range.Text) || HeaderObj.Range.Text.Equals("\r"))))
{
if(HeaderObj.PageNumbers.NumberStyle == WdPageNumberStyle.wdPageNumberStyleNumberInDash
|| HeaderObj.PageNumbers.NumberStyle == WdPageNumberStyle.wdPageNumberStyleUppercaseLetter
|| HeaderObj.PageNumbers.NumberStyle == WdPageNumberStyle.wdPageNumberStyleUppercaseRoman
|| HeaderObj.PageNumbers.NumberStyle == WdPageNumberStyle.wdPageNumberStyleNumberInCircle
|| HeaderObj.PageNumbers.NumberStyle == WdPageNumberStyle.wdPageNumberStyleLowercaseRoman
|| HeaderObj.PageNumbers.NumberStyle == WdPageNumberStyle.wdPageNumberStyleLowercaseLetter
|| HeaderObj.PageNumbers.NumberStyle == WdPageNumberStyle.wdPageNumberStyleHindiLetter1)
{
PageNumber = true;
}
}
}
}
}
catch (Exception e) { }
But the checks cannot determine if it is Page number or not. What should I do to determine if it has page numbers?
You should check the Header and the Footer of Section using the PageNumbers.Count propertie.
private bool HeaderOrFooterHasPageNumber(Word.HeaderFooter headOrFooter)
{
if (headOrFooter != null)
return headOrFooter.PageNumbers.Count > 0;
else
return false;
}
And you can call this like...
bool hasNumberPages = false;
Word.Document doc = WordApp.ActiveDocument;
try
{
Word.HeaderFooter headOrFooter = null;
Word.Section section = null;
for (int i = 1; i <= doc.Sections.Count; i++)
{
try
{
section = doc.Sections[i];
if(section != null)
{
headOrFooter = section.Footers[Word.WdHeaderFooterIndex.wdHeaderFooterPrimary];
hasNumberPages = HeaderOrFooterHasPageNumber(headOrFooter);
if (hasNumberPages)
break;
headOrFooter = section.Footers[Word.WdHeaderFooterIndex.wdHeaderFooterEvenPages];
hasNumberPages = HeaderOrFooterHasPageNumber(headOrFooter);
if (hasNumberPages)
break;
headOrFooter = section.Footers[Word.WdHeaderFooterIndex.wdHeaderFooterFirstPage];
hasNumberPages = HeaderOrFooterHasPageNumber(headOrFooter);
if (hasNumberPages)
break;
headOrFooter = section.Headers[Word.WdHeaderFooterIndex.wdHeaderFooterPrimary];
hasNumberPages = HeaderOrFooterHasPageNumber(headOrFooter);
if (hasNumberPages)
break;
headOrFooter = section.Headers[Word.WdHeaderFooterIndex.wdHeaderFooterEvenPages];
hasNumberPages = HeaderOrFooterHasPageNumber(headOrFooter);
if (hasNumberPages)
break;
headOrFooter = section.Headers[Word.WdHeaderFooterIndex.wdHeaderFooterFirstPage];
hasNumberPages = HeaderOrFooterHasPageNumber(headOrFooter);
if (hasNumberPages)
break;
}
}
finally
{
if(headOrFooter != null)
{
Marshal.ReleaseComObject(headOrFooter);
headOrFooter = null;
}
if (section != null)
Marshal.ReleaseComObject(section);
}
}
}
finally
{
if (doc != null)
Marshal.ReleaseComObject(doc);

I have a product ordering page with various product option dropdownlists which are inside a repeater. The "Add To Cart" button is "inactive" until all the options have a selection. Technically, the "Add To Cart" button has two images: a grey one which is used when the user has not selected choices for all options available to a product and an orange one which is used when the user has made a selection from each dropdownlist field.These images are set by the ShowAddToBasket and HideAddToBasket functions.
The dropdownlist fields are connected in that a selection from the first field will determine a selection for the second and sometimes third field. If the second field is NOT pre-set by the first field, then the second field will determine the value for the third field. The first dropdownlist field is never disabled, but the other two can be based on what options have been selected.
There are a few products that have all 3 of their dropdownlists pre-set to certain choices upon entering their page. This means they are all disabled and cannot be changed by the user. Regardless of whether the user enters in a quantity or not, the "Add To Cart" button NEVER activates. I cannot for the life of me figure out how to change it so that, in these rare circumstances, the "Add to Cart" button is automatically set to active once a quantity has been entered. The dropdownlists still have options selected in these pages--it's just that they are fixed and cannot be changed by the user.
Is there anyway I can get the selected value or selected index of these dropdownlist fields upon entering a product page? I want to be able to check to see if they are truly "empty" or if they do have selections made so I can set the "Add to Cart" button accordingly.
Any help would be great because I'm really stuck on this one! :(
Here is the code behind (I removed a lot of the unimportant functions):

Try accessing the values in the Page_Load event. I don't believe the values are bound yet in Page_Init
I am doing an assignment involving the creation of a simple Quiz type form application. However, whenever I run the program, only the first answer shows for a multiple question and I cannot for the life of me figure out why.
This is the contstructor:
MultipleChoice dlg =
new MultipleChoice(
new Question("What is the capital of Zimbabwe?",
new Answer("Paris", false),
new Answer("Washington D.C.", false),
new Answer("Harare", true),
new Answer("Cairo", false),
new Answer("N'Djamena", false)));
if (dlg.ShowDialog() == DialogResult.OK)
{
if (dlg.Correct) MessageBox.Show("You got something right!");
else MessageBox.Show("You couldn't be more wrong");
}
And this is the Question Form Code:
private Question Q;
public MultipleChoice (Question q)
{
Q = q;
InitializeComponent();
textPrompt.Text = Q.Prompt;
if (Q.A != null)
{
radioA.Text = Q.A.Prompt;
}
else radioA.Hide();
if (Q.B != null)
{
radioB.Text = Q.B.Prompt;
}
radioB.Hide();
if (Q.C != null)
{
radioC.Text = Q.C.Prompt;
}
radioC.Hide();
if (Q.D != null)
{
radioD.Text = Q.D.Prompt;
}
radioD.Hide();
if (Q.E != null)
{
radioE.Text = Q.E.Prompt;
}
radioE.Hide();
}
public bool Correct
{
get
{
if (Q == null) return false;
if (Q.A != null && Q.A.Correct && radioA.Checked) return true;
if (Q.B != null && Q.B.Correct && radioB.Checked) return true;
if (Q.C != null && Q.C.Correct && radioC.Checked) return true;
if (Q.D != null && Q.D.Correct && radioD.Checked) return true;
if (Q.E != null && Q.E.Correct && radioE.Checked) return true;
return false;
}
}
Where have I gone wrong?
There is no else for any option after A:
if (Q.B != null)
{
radioB.Text = Q.B.Prompt;
}
radioB.Hide(); //This is **always** going to be called - hiding radioB :)
Should be:
if (Q.B != null)
radioB.Text = Q.B.Prompt;
else
radioB.Hide();
