I have a label and a checkbox that reside in a datagrid. When the checkbox is checked (OnCheckedChanged), I would like to send the Checkbox value and the label.text to a method. I don't have a way of retrieving the values. I've seen a lot about retrieving all of the values from a datagrid, (myDataGrid.Items), but am not sure how to get the value for a specific row in the datagrid.
View 1 RepliesThis morning I posted a question w.r.t Radio Buttons, but the requirement changed so I'm posing a similar question.
I want to have a checkbox in a datagrid.
Suppose I click on one of the checkboxes and then realize i need to click on another, the screen has to automatically uncheck the previously clicked checkbox and then check the newly clicked checkbox.
In other words I need to clear previously checked checkboxes and check the recently clicked checkbox.
Also, I need to update a label in the page with a value associated with the row of the checked checkbox.
I should not be using a javascript to do this.
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):

How bind the data through checkbox if checkbox checked is true
View 3 RepliesI am using following code on SelectedIndexChanged of Dropdownlist in GridView for filling txtCallCompletion.Text. When i am selecting first time it is coming correct and i am changing value of txtCallCompletion then i am selecting second checkbox then previous checked checkbox's txtCallCompletion value will be same as it is.
how to solve this issue in gridview checkbox i already checked.

i have a database of values that I am rendering in a table via the repeater control. (Previously I was using a gridview but I know require a repeater) I have a checkbox being 'repeated' for each record and I can get the id of each row to do some logic, but what I cannot get is whether it is checked or not as the value is null. As the database has no null values, I can only asume it is not binding for the checkboxes as current true values do not have a check in the box. The onCheckedChanged event carries out the logic required to change whether record is disabled via the database. With a gridview
Checked='<%# Bind ("Disabled")%>' was enough
<td
class="GridCentre"[code]....
is this done with the itemdatabound event? and how is it done?
Using CheckBox in DataList to set checked property
View 3 RepliesI have a formview in edit mode, with submit button and checkbox. I want to click the button and have it test to see if the checkbox is checked. The ID of the checkbox is "TestCheckBox". I figured it would be something like, If TestCheckBox.Checked then, but if I type in TestCheckBox it says it's not declared, even though it is a control in the formview.
View 5 RepliesI was trying to find out if there are any check boxes checked in the datagrid, if non of them is checked it should show me an alert to select atleast one.
My problem starts when there is paging in datagrid...
not able to check the entire datagrid at a time in itemDataBound event for the checked check boxes.
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.

And here is my code behind:

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?

View 4 RepliesI 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.

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.
i got checkbox in gridview which put inside the itemtemplate. the problem is when i tick on the checkbox, the value for checked property still is a false value. Wat;s wrong?

how do i write a javascript fucntion to check whether the checkbox was checked or not?
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!
The code is as follows...
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="dsResults"
BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px"
CellPadding="3" OnRowUpdated="GridView1_RowUpdated">
<Columns>
<asp:TemplateField HeaderText="COMPLIANT" SortExpression="RESULTS">
<EditItemTemplate>
<asp:CheckBox ID="CheckBox2" runat="server" Checked='<%# Bind("RESULTS") %>' />
</EditItemTemplate>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" Checked='<%# Bind("RESULTS") %>'
Enabled="False" />
</ItemTemplate>
</asp:TemplateField>
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.
