Hello Brad,

When at template Column, the ID of checkbox has been changed. You could not get "chk" in clientside. If you try to view source at the browser and search for "chk", you should be able to find the changed id.

Also, I think that you wanted to get the checked rows, not checked column in your scenario.
We have a WebGrid Sample >> PreserveCheckedRows.aspx. In order to do this, you will need to use our ISRowChecker feature.
You can use this sample to retrieve the checked rows value from server side. 

Or you can use my attached sample as reference. I showed how to get checked rows via client side and server side.
Hope this helps.

Hi Handy,

I don't quite understand this example. I would have expected the GetCheckedRows method to return WebGridRow objects but instead, I get an arraylist of empty strings. I'm not sure what I can do with an arraylist of empty strings. Ultimately, I need to know which rows are checked and then I need to retrieve data from those rows. I don't know if I can accomplish that with this method. Am I overlooking something?

Hi Brad,

It does return on the checked rows. Could you provide your runable sample which replicate this issue? I need it toinvestigate the differences.

Normally, when used GetCheckedRows in ISRowChecker or Multiple selection features, the method shall return the checked or selection rows.
So, my question, Do you also use ISRowChecker in your sample?

In my previous sample, I used ISRowChecker and GetCheckedRows() should be able to return the object.

Handy,

Here are the relevant code snippets

<ISWebGrid:WebGridColumn Name="Fasta" Caption="Fasta" ColumnType="CheckBox" IsRowChecker="true" Bound="false" Width="50" />

Dim al As ArrayList = WebGrid1.RootTable.GetCheckedRows()

So I have a grid with a bunch of data and the first column in the grid is a checkbox column with isRowChecker set to "true." I check two rows and click an <asp:Button instance and in the "Click" event handler for that button, I am trying to get the checked rows. When I call "GetCheckedRows," I get an arraylist of empty strings. It should not be too hard to replicate as there is nothing that I am doing that is out of the ordinary from what I can tell.

Thanks,

Brad

Handy,

I am able to get the checked data key values the following way

            For Each str As String In WebGrid1.RootTable.GetCheckedRows()
                Dim row As WebGridRow = Me.WebGrid1.RootTable.Rows.GetRowByKeyValue(str)
                cList.Add(row.Cells.GetNamedItem("ID").Text.Trim())
            Next

The difference was that I didn't have a DataKeyField on my grid and didn't have PersistRowChecker set to True.

So I am all set now on this one.

Thanks for your help.

Brad
