i have two layutflowpanel
1-flowpanel_category
2-flowpanel_products
when i use nested for loop inside button click to get products from current select category another flowpanel_prd not showing that products from categorey maybe i have some mistake in the some point
i set inside InitialComponents this code to retrive all items from category to put it inside flowpanel_category
//get all category and set it all to flowpanel_cat
FLOWPANEL_CAT.Controls.Clear();
try
{

I want to display the row details of Gridview when user click the button of template field. I got the output to display the button in a Gridview using template field. But when user click the button it reload the page and display the empty template with rows.

Output before user clicks the Button
output1
After clicks the button(first button)
output2
I already did like this before,but that was small one not more complex code like this. that was working fine. Now What i did wrong here?.
Thanks
I think ViewDetails() method is not calling when user clicks the button
I have a question regarding creating controls in runtime in ASP.NET 4.0. I'm building a application and in admin.aspx page I have multiple controls (DropDownLists) which are dynamically created with values from a Sql database.
I know that for having events fired for dynamically created controls, I have to create this controls in Page_Load() or in Page_Init().
My project has a Master Page, in which I have a 1 second timer which updates a clock. This timer event calls my admin.aspx Page_Load() function, so my method which creates dynamic controls it's called every 1 second - connection to database is made every one second, please look below to my code.
It's a good practice to do that? Can you please propose some ideas?
protected void Page_Load(object sender, EventArgs e)
{
_SinopticBackgroundColor = ConfigurationManager.AppSettings["SinopticBackgroundColor"];
panelContent.Style.Add("background-color", _SinopticBackgroundColor);
Control c = GetControlThatCausedPostBack(this);
if (c != null)
{
if (c.ID.Equals("btnManageCategory"))
hfPageManage.Value = "category";
else if (c.ID.Equals("btnManageDevices"))
hfPageManage.Value = "device";
}
if (hfPageManage.Value.Equals("category"))
{
cbTreeViewGroup.Visible = false;
UpdateSinopticCategoryManager(TreeView1.SelectedNode); //this is the functions which loads controls from database..
}
else if (hfPageManage.Value.Equals("device"))
{
cbTreeViewGroup.Visible = true;
}
else
{
cbTreeViewGroup.Visible = false;
}
if (!Page.IsPostBack)
{
LoadFunctions(); // loads some values from database into datatables
}
else
{
}
}
And here is the functions which creates controls

It's about this: DropDownList categList = new DropDownList();

Hiiii,
In the following image the table & controls in it are generated dynamically.
Table is created onclick of "create table" button using values from dropdownlist which has no. of rows as values.
How can I get particular “Fileupload” & “Upload” button’s ID.
On click of “upload” button only fileupload control in same row as of that button should be accessed & it should not loop through all the fileupload controls in the table.
In my code, when I click Upload button in lower rows(say 3rd row) then it uploads the file selected in upper fileupload controls( here 1st n 2nd row along with 3rd row ) also.
I don’t want this. I just want to upload file from filupload control in the same row of clicked button.

plz Help me Out !!!
Thanx in Advance...
why not store a Row ID in the command argument for the button and then when the button is click you can use this to loop through all the rows untill the id matchs the row you are looking for, for example
foreach (DateRow test in table.Rows)
if ((test.findcontrol(uploadbutton) as Button).commandArgument = (Sender as Button).commandArgumrnt
{
//do stuff here
}
else
{
\\ do nothing
}
Hope this helps
I have a method that creates textboxes depending on the number of parameters values that the user has to enter.And its working fine. The problem is that when the user clicks Ok i want to take the value that the user entered in these textboxes and replace them in a string. When am searching these textboxes to get the text value from them am not finding them. How do i get these values to continue my project? the code is:
protected void btnPreview_Click(object sender, EventArgs e)
{
lbHeader.Text = "Template Designer";
divQueryBuilder.Visible = false;
divTemplateDesigner.Visible = false;
divFloating.Visible = true;
if (txtQuery.Text.Contains("WHERE") || txtQuery.Text.Contains("where")||txtQuery.Text.Contains("Where"))
{
string[] splitter=new string[10];
splitter[0]="Where";
splitter[1]="WHERE";
splitter[2]="where";
splitter[3]="AND";
splitter[4] = "and";
splitter[5] = "And";
string[] condition=txtQuery.Text.Split(splitter, StringSplitOptions.None);
int numberOfParameters = condition.Length - 1;
string[] Condition1 =null;
Label[] newLabel = new Label[10];
TextBox[] txtBox = new TextBox[10];
for (int i = 0; i < numberOfParameters; i++)
{
string lbValue="lbValue";
string lbID=lbValue+i;
string txtValue = "txtValue";
string txtID = txtValue + i;
HtmlGenericControl genericControl = new HtmlGenericControl("br/");
Condition1 = condition[i + 1].Split('[', ']');
newLabel[i] = new Label();
txtBox[i] = new TextBox();
newLabel[i].ID=lbID;

txtBox[i].ID = txtID;

}
}
}

Please help. This has become a blocker for me.
Have a list of the added controls and use it when needed.
for (int i = 0; i < numberOfParameters; i++)
{
// ...
td2.Controls.Add(newLabel[i]);
td2.Controls.Add(genericControl);
td2.Controls.Add(txtBox[i]);
td2.Controls.Add(genericControl);
addedTextBoxes.Add(txtBox[i]);
// ...
}
And then from another part of your code:
var values = addedTextBoxes.Select(tb => tb.Text).ToList();
foreach (var txtBox in addedTextBoxes)
{
// ...
}
etc...
