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 have a GridView that I was previously populating via an ObjectDataSource, and this code was working perfectly (ie, when the checkbox was checked Checkbox.Checked = true):
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?
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 have a check-box-List which I bind to a master dataTable(DTA)... I have another dataTable (DTB) which has the values that needs to checked in the check-box-List... So I loop through all items in the check-box-list to see if it exists in the DTB and set checked = true for those items that exists. Now I want to show the checked items first in the Check-box-list box and the unchecked items below that. Is there any way I can do it... A similar solution for List-Box could also be helpful. A Javascript hint is welcome too.
I think this must be easy... I need to read if a certain checkbox is checked or not, but it's mandatory to me use the findcontrol.Can someone help me ? maybe it's just necessary to complete the code bellow:
Control cb = FindControl(cols[i].id_coluna.ToString());
Then when the user clicks an Edit button I run a script that enables all the checkboxes (which works fine), and then when the user then clicks on a checkbox the tick is appearing or disappearing as it should.
The problem I'm having is that when I try to read the value of the checkbox from the codebehind:
I have a calendar control that has a checkbox control added to each cell on dayrender. A user will check the dates that they want to add an event for and click a button that will display the modaldialog box where the user will enter the event for the selected dates. I'm having trouble looping through the calendar dates to get the checkbox contol's checked property.
I have a ASP.Net page that has a gridview control. This gridView control has a checkbox controls. I would like to assign a boolean value from a database field to the Checked property- Checked='<%# Bind("RESULTS") %>'.
When page loads,I get error - Specified cast is invalid!
Note: If a constant value is passed at design time it works fine. But i want to assign the value at runtime using Bind.
Environment details: VS 2008, ASP.NET 2.0 and .Net Framework 3.0 & C# language.
I tried returning values like 0s and 1s, Ys and Ns and True and False from a database field. But i still get the above mentioned error.
I tried retreving the value in OnRowDataBound event using Eval, since Bind is not available in code behind. But it would make the field readonly and i cannot edit and update the Results field.
Even though there is a value returned by the query why does the Checkbox does not assign the value using <%# Bind("Results") %> to Checked property instead throws error - Specified cast is invalid.
how i can edit and update Checkbox.
where did the Bind method of ASP.Net 1.x is moved? How can i use Bind in code behind of ASP.Net 2.0?When i type DataBinder the intellisense shows Eval and other stuff but i don't see Bind that would solve the problem of two- way binding.
but since the value is 'false', it doesn't seem to cast to boolean. What should I do? I don't like checking for == "false" and then converting to boolean. is there a cleaner way? Update All I am doing is:
if (Convert.ToBoolean(request.Form["somecheckbox"])) { }
In internet exporer 8, every time the dialog box is opened the textbox controls increase in size! None of the other items do: label and button. If it makes any difference - dialog is created when a certain item is selected within a select list.
Th dialog is themed from the theme roller site and the controls styled using an external css file.

I have a BING MAP in web app. which is of JavaScript or Jquery. And also I have a DataGrid in same page. Data Grid is populated with Address ROWS. A check box is also there as ItemTemplate for DataGrid.
Now after dataGrid binded with data source, and when user clicks on check box, that particular address should show on BING MAP.
My question is,
How to invoke a JavaScript function when user checks checkbox in data grid. Which data Grid events suits my scenario? Also can I do this on client side without going to server side and call JS function?
I have a simple form that uses jQuery validation to notify the user of input errors, etc. When I add an ASP.NET CustomValidator to the form, it causes the page to postback and skip the jQuery validation. I need the form to not be submitted to the server until the client-validation is correct. Has anyone seen this before?
I have a checkbox on my project and I have textboxes as well. I tried some jquery code as you can see below for this function;
