i am working on a project and i have a gridview and a radiobutton in gridview and what i want is,i want to send the selected rows value to database on the click of the button but i am getting an error as object reference not set to the instance of an object.
As my code is
cs code on the click of the button
protected void btn_selectgridview_Click(object sender, EventArgs e)
{
int k = 0;
//Checkther whether atleast one check box is selected or not
for (int i = 0; i <=gvrepair_details.Rows.Count-1; i++)
{
GridViewRow row = gvrepair_details.Rows[i];
RadioButton rb = (RadioButton)row.FindControl("CheckBox1");
if (rb.Checked == true)
{
k++;
}
}
if (k == 0)
{
Page.ClientScript.RegisterStartupScript(this.GetType(),Guid.NewGuid().ToString(), "<script language=JavaScript>alert('select the value in grid');</script>");
return;
}
for (int i = 0; i <=gvrepair_details.Rows.Count-1; i++)
{
string bookname = gvrepair_details.Rows[i].Cells[1].Text;
string categoryname = gvrepair_details.Rows[i].Cells[2].Text;
string subcategory =gvrepair_details.Rows[i].Cells[3].Text;
string shelf_no = gvrepair_details.Rows[i].Cells[4].Text;
string isbn = gvrepair_details.Rows[i].Cells[5].Text;
string edition = gvrepair_details.Rows[i].Cells[6].Text;
string status = gvrepair_details.Rows[i].Cells[7].Text;
GridViewRow row = gvrepair_details.Rows[i];
RadioButton rb = (RadioButton)row.FindControl("CheckBox1");
if (rb.Checked == true)
{
InsertData(bookname, categoryname, subcategory, shelf_no, isbn, edition, status);
}
}
}
void InsertData(String bookname, String categoryname, String subcategory,String shelf_no,String isbn,String edition,String status)
{
try
{
sql = "insert into library_repair(bookname, categoryname, subcategoryname, shelf_no, isbn, edition, status)values('" +bookname+ "','" +categoryname+ "','" +subcategory+ "','"+shelf_no+"','"+isbn+"','"+edition+"','"+status+"')";
ds = obj.openDataset(sql, Session["SCHOOLCODE"].ToString());
}
catch (Exception ex)
{
Response.Write(ex.ToString());
}
}
I reformulated you first function (Code may contains syntax error since haven't run it):
protected void btn_selectgridview_Click(object sender, EventArgs e)
{
int k = 0;
int checkBoxColumnIndex = 2; //Here you should specify the cell containing the checkBox
foreach (GridViewRow item in gvrepair_details.Rows)
{
RadioButton rb = (RadioButton)item.Cells[checkBoxColumnIndex].FindControl("CheckBox1");
if (rb != null && rb.Checked) //Check if rb is null
{
k++;
string bookname = item.Cells[1].Text;
string categoryname = item.Cells[2].Text;
string subcategory = item.Cells[3].Text;
string shelf_no = item.Cells[4].Text;
string isbn = item.Cells[5].Text;
string edition = item.Cells[6].Text;
string status = item.Cells[7].Text;
InsertData(bookname, categoryname, subcategory, shelf_no, isbn, edition, status);
}
}
//Checkther whether atleast one check box is selected or not
if (k == 0)
{
Page.ClientScript.RegisterStartupScript(this.GetType(), Guid.NewGuid().ToString(), "<script language=JavaScript>alert('select the value in grid');</script>");
return;
}
}
Note the checkBoxColumnIndex. CheckBox1 index should be provided.
try this
if (((RadioButton)gvrepair_details.Rows[i].FindControl("CheckBox1")).Checked == true)
{
k++;
}
instead of
if (rb.Checked == true)
{
k++;
}

I have a listbox with a list of items that get loaded when you navigate to a certain page. Then I have an on click that passes parameters to an AddProducts method. That method is what loops through all selected items and inserts values from the fields filled in as well as takes the values from the listItems and adds them as parameters to a stored procedure.
The problem I'm running into is that when looping through the listItems
if(selectedItem.Selected) is returning false, but in my method where I load the listbox I initialize a SelectedValue so I'm not sure why it's giving me the error message I have for no selected items. I was able to get it to work yesterday before I moved LoadListBoxCategories outside of LoadAddData but unsure as to why that would have any effect to if(listItem.Selected).
I'm relatively new to asp.net so any help/ explanation as to why my code isn't working is extremely appreciated. I've spent the last three days trying to figure this out and haven't found a solution that works.
Code:
Page_Load:
protected void Page_Load(object sender, EventArgs e)

gvTextInputs.RowEditing += new GridViewEditEventHandler(gvTextInputs_RowEditing);

string productId = Request.QueryString["productid"];
/* Add Mode */
if (!string.IsNullOrEmpty(pageId))
{
SetMode(MODE_ADD, "");

LoadListBoxCategories(pageId);
}
else if (!string.IsNullOrEmpty(productId))

if (LoadProductData(productId, out imageServer))
{
InitImageGridview();
InitTextGridview();
InitStaticGridview();
SetMode(MODE_EDIT, imageServer);
SetImageServer(imageServer);

The list box instance is recreated on the server-side during the postback (as well as entire page). You do not set the selected items in the Page_Load event handler - if (!IsPostBack) goes to else branch. This is why you don't see them.
Ok,
lstCategoriesBox.Items.Clear();
Ok, above goes nuclear - blows out the list, blows out the selection.
Ok, that's fine
lstCategoriesBox.Items.Add(new ListItem("--Select--", null));
lstCategoriesBox.DataTextField = "productName";
lstCategoriesBox.DataValueField = "CombinedValue";
Ok, above adds a new item. Should be ok, but one should setup the lb BEFORE adding any data - including that "--select--" row.
It just makes sense to "setup" the lb and THEN start adding data, right?
However, But, if above works - ok, then lets keep going, but I would setup the lb before adding any rows of data. Say like this:
lstCategoriesBox.DataTextField = "productName";
lstCategoriesBox.DataValueField = "CombinedValue";
lstCategoriesBox.Items.Add(new ListItem("--Select--", null));
Now, the next line:
lstCategoriesBox.SelectedValue = curCategoryProductTypeId;
Ouch! - we just cleared the lb, and now we trying to set it to a value? You can't do that - the lb just been cleared, right? You would need to load up the lb first, and THEN you can set it to the selected value, right?
I might be missing something here, but that lb needs to be loaded up with valid data BEFORE you attempt to set the selected value?
To test first, change following
Outcome Category.InnerText = list CategoriesBox.SelectedValue;
to
Category.InnerText = Request.Form["CategoriesBox-ClientID"]
If the data is coming in correctly, the list view cleared or reloaded when between reload and click events the page.
UPDATE: I just figured it out! So stupid but when I check if(selectedItem.Selected) since I'm looping through the ListBox items it starts at the first index of the ListBox and since the first isn't selected then that if goes to the else block. Remove the else and it works fine
I tried to add data from data set to access database with TableAdapter.Update() method, but it doesn't function. Here is my code. I have DataGridView on my Windows Form, Table (Users) are binding to DataGridView.
private void btnScanGroups_Click(object sender, EventArgs e)
{
foreach (UserGroup group in g)
{
string groupName = group.Name;
string groupID = group.Link;
int userID = 1;
groupsTableAdapter.InsertGroupsQuery(groupName, groupID, userID);
text = text+"\n added "+groupName + " - " + groupID;
richTxtBoxStatus.Text = text;
}
groupsTableAdapter.Fill(facebookGroupAutoPostDBDataSet.Groups);
groupsBindingSource.EndEdit();
groupsTableAdapter.Update(facebookGroupAutoPostDBDataSet.Groups);
}
Here i have some code that works fine. Except the thing i need it do the most right now.
I have a label which i've named (lblProfileID) and i need this label to display the (ProfileID) that matches the (ProfileName) depending on the selection i've made in the combobox where all the Profilenames are stored.

Any help will be greatly appreciated...
Your sb.AppendFormat format string expects 5 items.
You said ds.InsertPlan() has the following signature, and the arguments map to InsertPlan() not AppendFormat(). However, InsertPlan() returns a single int, so AppendFormat() only has 1 argument, an int value.
public virtual int InsertPlan(
string Plan_ID, <- "1"
string Place_1, <- splitItems[0]
string Place_2, <- splitItems[1]
string Distance, <- splitItems[2]
string Date, <- splitItems[3]
System.Nullable<System.DateTime> Created_Time, <- DateTime.Now
System.Nullable<System.DateTime> Updated_Time, <- DateTime.Now
string Created_by, <- user
string Updated_By, <- user
string Version_Status, <- "Nil"
System.Nullable<int> p3 <- 1
)
Your code:
sb.AppendFormat("{0}('{1}','{2}','{3}','{4}'); ",
ds.InsertPlan("1", // <-- unless InsertPlan() returns an array, then this
// is only 1 argument to the outer function
splitItems[0],
splitItems[1],
splitItems[2],
splitItems[3],
DateTime.Now, DateTime.Now, user, user, "Nil", 1
)
);
is like:
sb.AppendFormat("{0}('{1}','{2}','{3}','{4}'); ",
1); // only {0} has a argument
// {1} ... {4} do not

I think you are setting a value in ddlMonth but ddlMonth do not have that binded value.. Try to bind list of values in your ddlMonth before setting a value to it
Please next time format the code before posting.
For the problem I think the solution is to put the region where you set the SelectedValue inside an
if(!isPostback){...}
I suggest you to take a look to the documentation about page lifecycle, because the explanation is that the Page_Load in executed not only the first time you load a page, but also for every postback (if you don't use the if(!isPostback){...}
