Data Controls :: Checkbox In GridView Always Returning Checked False In Code Behind
Nov 6, 2013
I'm having trouble getting selected rows in asp.net. i tried to debug it and found out that the answer to "chkRow.Checked" is always false eventhough it is selected. I'm new to asp.net.here is my code.
Protected Sub btnApproveYes_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnApproveYes.Click
Dim modID As String = String.Empty
For Each row As GridViewRow In gvModule.Rows

I a using Gridview bind to a dataset. For this example, I am only setting up two columns.
1. Edit button
2. A template field that will display "No" and in Edit mode will show a checkbox.
When I run this code... the page is displayed... I click on the edit button... the row changes to edit mode and I CLICK the checkbox (can see a it checked).Then click on "Update" Button... which takes me to GridView1_RowUpdating event. If I check the status of the "box"... it's checked status is ALWAYS false Why?

There is a Gridview in my web page with select button as below:
<div class="test01" style="height:200px;overflow-y:scroll;overflow-x:hidden" align="center">
<asp:GridView Width="100%" ID="GAsset" runat="server" AutoGenerateColumns="False" DataKeyNames="AssetId">
<Columns>
<asp:BoundField DataField="AssetId" HeaderText="AssetId"/>
<asp:BoundField DataField="AssetName" HeaderText="Asset Name"/>
[Code] ....
When I am selecting any row of Gridview using checkbox and clicking on "Select" button, It is showing ch.checked= false
code is below:
protected void btnSelect_Click(object sender, EventArgs e) {
foreach (GridViewRow row in GAsset.Rows) {
CheckBox ch = (CheckBox)row.FindControl("chkSelect");
if (ch.Checked && ch != null) {
string key = Convert.ToString(GAsset.DataKeys[row.RowIndex].Value);
[Code]....
I also tried debugging my code using break points but it is showing ch.Checked = false everytime, dont know why.

I came across the following given a asp.net page containing
<div id='test'>
<input type='checkbox' id='ch1' name='ch1' runat=server />
<input type="button" id="view_test" />
</div>
and the following jquery code to show this div in a dialog
$("#view_test").click(function() {
$("#test").dialog({ show: 'slide', width: 600, title: 'View Check' });
});
If view_test button was clicked, initializing the dialog, before the form post backs the checkbox ch1.Checked property in .Net is always False. However if you just postback without initializing the dialog it works as expected.

I need to make sure only one checkbox gets checked in a GridView. I have tried a solution on here, but I get an error. The other is looping through the checkboxes in the gridview to get the value, in this case, a date.

I have problems with GridView control which has template field with checkbox in it. My primary concern is that same code works for all the other GridView controls I have in different webforms, but not in this one.
This code is supposed to get the identities (ID column in GridView) and then get the values of first two selected and finally redirect them to another webform as querystrings. I double checked the GridView and they are identical (except they are binded to different datasource).
Here is the code that doesn't work:

I am trying to pull data from database and populate a gridview. I did it like this:
<asp:CheckBox ID="chkItem" runat="server" Enabled="false" Checked='<%# (DataBinder.Eval(Container.DataItem,"Em").ToString()=="True"?true:false) %>' TabIndex="1" />
I need to have an update on the gridview, so instead if using Eval, I need to use Bind. translate the line above to a bind function?

I have a gridview control in which there is a column with checkbox. I will have to delete the rows of the grid selected by the checkbox. After the delete operation i am re-binding my grid we new datasource to populate latest data. The data is comig up correctly and the no of rows in the grid are also correct.
But the problem is that, if i select row 1 to delete and click on delete button, row 1 is deleted, grid is refreshed with new list, but row 2 checkbox is getting automatically checked. I don't know how this is happening. I have tried of writing code to uncheck all checkboxes after i rebind the grid. None of them are working. When i debug and see the items are actually showing as checked=false, but on the screen the check box is checked.

I have a GridView with a Template Field set to Checkbox. Issue is; when I click the asp:button I placed beneath the GridView to update the database, I do not get a checked value on the returned button. So it just skips my code and nothing happens.
[Code]....
Then I have my Method.
[Code]....
So when the code gets to this line if (cb != null && cb.Checked == true), the value is always False even for the checked box.

In the Asp.Net Gridview, I am having a checkbox in each and every row for Printing.
I read and test this code found in this link: [URL]
and works really nice, but I would like to use each checked select row for printing instead of clicking "print" each time I print the row. If I want to print selected checkboxes row, I want to see a window open for printing the checkboxes rows I selected in the gridview.
I also tried this link: [URL]
but doesn't display a new window for printing.
