Web Forms :: How To Change The Data In A DDL Based On If A Checkbox Is Checked Or Not
Aug 18, 2010
I have a DropDownList for suppliers; suppliers can be active, or inactive. I have a checkbox to toggle between all suppliers, or just active suppliers.
My front code is:
[Code]....
My back code is:
[Code]....
BindDDL() also gets called in page load. The checkbox is unchecked by default, so when I first navigate to the page, only the active suppliers will be selected. When I click the checkbox, the page post posts back, but doesn't change the data in the DropDownList (still only active suppliers).
I've run through the debugger and it's hitting the right if statement, just not updating, and I don't know why. I've tried a Show all/active dropdownlist and event handlers, and neither do what I want them to do. How do I fix this?
Fix: BindDDL() method

I used below code fo radiobutton to inserting data in database
string price = RadioButton2.Checked ?"1": "null";
SqlCommand _cmd = new SqlCommand("insertproduct2", _cn);
_cmd.CommandType = CommandType.StoredProcedure;
_cn.Open();
_cmd.Parameters.AddWithValue("@Price", price);
_cn.Close();

else insert "Null" but when I wrote below code
string Off = checkbox1.Checked ? "1" : "null";

I am trying to retrieve a value from the row based on the user checking the checkbox but the only way it works is opposite of what I think it should be. The problem is I can only get the values if I set "If RowCheckBox.Checked = False" So I have rows returned in the gridview:
row1, record1
row2, record2
row3, record3
I want to check row1 and row3 and grab the values record1 and record3 I use:
Dim str As String
Dim row As GridViewRow
Dim index As Integer = dgrdSearchResults.SelectedIndex
lblStatus.Text = index
For Each row In dgrdSearchResults.Rows
If index = -1 Then
index = 0
End If
Dim RowCheckBox As CheckBox = CType(dgrdSearchResults.Rows(index).FindControl("chkResults"), CheckBox)
If RowCheckBox.Checked Then
str = dgrdSearchResults.Rows(index).Cells(2).Text
lblStatus.text = str
End If
index += 1
Next
With this code I basically step out even when I have rows checked. zaybe I am looking to much but I cannot get it to return the values I need unless I change "If RowCheckBox.Checked " to If RowCheckBox.Checked = "False"

I am using a datalist with checkbox and datalist is in a panel. I am poping the panel by using ajax modal pop-up. When we check the checkbox the checkedchange event is firing. But, when we uncheck the checkbox the event is not firing. It is user control and it is in update panel.

I have two checkboxes on my form.
- How can I uncheck a checkbox using client side code when the other checkbox is checked?
- Is there a way to check server side on form submission that at least one check box is checked?

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.

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?

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 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 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 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.
