Forms Data Controls :: Get Value Of Label When Checkbox Checked

Jul 22, 2010

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.

Forms Data Controls :: Checkboxes In Datagrid / Update A Label In The Page With A Value Associated With The Row Of The Checked Checkbox

Aug 26, 2010

This 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.

Forms Data Controls :: Binding To Checkbox Checked When Using A Repeater

Dec 20, 2010

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?

May 14, 2010

I 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.

I a using Gridview bind to a dataset. For this example, I am only setting up two columns.

Forms Data Controls :: Checkbox In GridView Isn't Getting The Checked Value Correctly?

Jan 18, 2011

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:

Forms Data Controls :: Checkbox Automatically Checked After Delete In GridView

Apr 23, 2010

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.

Forms Data Controls :: GridView Checkbox Not Retuning Checked Value Correctly

Sep 7, 2010

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.

Forms Data Controls :: Cannot Assign Values To Checked Property Of Checkbox At Runtime

Apr 22, 2010

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.
