I have column:

    
                    <telerik:GridTemplateColumn HeaderText="Profit"><ItemTemplate> 
        
                        <asp:Label ID="profit" runat="server"></asp:Label></ItemTemplate> 
        
                    </telerik:GridTemplateColumn>

And I want to update each label in this column from JavaScript function.

For example, event onkeyup for some textbox outside the Grid.

After enter some value, all values in column Profit is changing.

How can I get this in Javascript and iterate through all cells in "Profit" column?

Filtering MasterTableView When RADGrid is binded to List Object

Hi,

Binding RADGrid to list object in general case scenario works good. But I have a situation where I am using the RADGrid for showing hierachical data and I am using self referencing telerik RADgrid grid. For the first level my parentFileID property has null value. so I want to filter my records for masterTableView with FileParentId.

The below code gives error when I bind the grid to a list object.

if

(Assembly.GetAssembly(typeof(ScriptManager)).FullName.IndexOf("3.5") != -1)

{

grdsearchresult.MasterTableView.FilterExpression =

@"it[""FileParentID""] = Convert.DBNull";

}

else

{

grdsearchresult.MasterTableView.FilterExpression =

"FileParentID IS NULL";

}

For Eg:

List

<SearchResult> listSearchResults=new List<SearchResult>();

grdsearchresult.DataSource = listSearchResults;

grdsearchresult.DataBind();
Here my datasource is List Type Object.The grid shows all records if I dont filter it.
So While binding the master records I get error index is not defined.?
Can't I bind the RADGrid with list object and provide filter to it.

Please reply.
Thanks,
Yuvika

Performance on firing of SelectedIndexChanged event

Hi,

I am using the RadGrid for AJAX and have enabled client-side select.

I have noticed that the process time for SelectedIndexChanged Event is directly proportional to the number of items in the grid.
Because I have an empty event handler that handles the SelectedIndexChanged Event, but the more items I have in the grid the longer the loading panel stays on the page.
Is this the case? If so, is there a way to optimize it?

Thanks,
Vincent

RadTextBox to use a real button

This is not really a question, but a suggestion that I think the RadTextBox control should have.

I like the RadTextbox's ability to show a button, but I was wondering if it would be possible to give it the ability to change the button type, so instead of the image button type to allow a normal button to be used where you could modify it's text property.

I think that would be a great addition to the control.

Suitable use for ListView

Hi

I'm having to create an admin form with a list of roles down the left and privilages across the top. At each intersection there will be a checkbox.

Would this be a suitable applcation for the listview control?

If yes do you have any examples as I'm struggling a bit, but it would help knowing it is possible before I spend too much time on it.

My original route was / is the use of nested repeaters.

[Solved] Filtering in RadGrid

Hi

Is it possible to only make some columns in a RadGrid filterable? (I have some hyperlinks that it doesn't make sense to filter).

Also, is it possible to make filtering non case sensitive?
