Extra blank Column, when the grid is expanded

Hi All,

I recently updated the radGrid Control from 2008.3.1314.34 to 2010.1.415.35. I am having a problem. When i expand the grid there is a blank column at the end of the Master grid. when i went on the apsx page i cannot find any blank column. I went in to the source code of the page and found that there is a blank column and the whold grid alignment is changed.
Also all the column are automatically resized to same width, i have to manually go in and change the width of each column

Is there a way to remove or hide this column or this is a bug ?
Is there a way to automatically change the size of the column to the atleast the size of the header text?

Give width and height = 100% to update panel created by RadAjaxManager

Hi,
I am using a Map and a RadAjax Manager. My map's height and width is set to 100% of its container.On using asp.net updatepanel I can give a css style and map renders perfectly. However, on using RadAjax manager map disappears.
The reason was RadAjax manager was wrapping my map with an update panel and unfortunately its width and height isnot set which caused map width and height = 0px.
How can I give a width and height value of 100% to updatepanel created by RadAjax manager, Is it possible to know the client ID of Update panel generated by RadAjax Manager that is wrapping the map, so that I can give a css style.

Any suggestion is appreciated.
Thanks
Prava

[Solved] RadGrid client side databind with programmatic structure is duplicating columns on postback

I am making a simple grid control using the radgrid which derives its structure(columns) from an xml and databind using client side web serivce. It works fine, render intially, paging/sorting work fine, I implement the client OnRowDataBound event and render hyperlinks also. When a postback happens from any other buttons on the page, the columns in the grid are duplicated.

Following is my simplified code:
aspx:

    
            <asp:Button ID="btnPostBack" runat="server" Text="PostBack" /> 
        
                    <telerik:RadGrid ID="grid" runat="server" GridLines="None" AllowFilteringByColumn="false" 
        
                        AllowSorting="true" AllowPaging="true" PageSize="10" AutoGenerateColumns="false">  
        
                        <ClientSettings> 
        
                            <DataBinding SelectMethod="GetResults" /> 
        
                            <ClientEvents /> 
        
                        </ClientSettings> 
        
                        <MasterTableView Width="100%" AutoGenerateColumns="false">  
        
                        </MasterTableView>

                        return objs;  
        
                    }

Note, this is a simplified version and the control has more complicated things which are not relevant here.

Thank you,

ToolTip response error

Hi,

I always get a pop up window with the error for the ToolTip. I added a function like this, but it still pops up !

    
            function OnClientResponseError(sender, args) { 
        
                            args.set_cancelErrorAlert(true); 
        
                        }

The error :
RadToolTipManager response error:
Exception=Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

Details: Error parsing near 'Telerik.Web.UI 2010.'.

How to solve such problem?

Custom Aggregate Function Problem

I'm having a problem calculating my custom aggregate sum function for nested groups.

For example, I have a product group, a product, and then several rows pertaining to that product (so there are two groupings: the main product group > then the individual product and its data). Then, for each grouping I have a footer which calculates the sum of the column based on the value of another column in that row.

What I'd like to see is something like this assuming a product group with 2 products. It would calculate the footer total for each product in that column if the first column's value is say 'Row 3' or 'Row 4' and then for the top product grouping (for 'Product Group 1') would calculate the values from the other footers.

Product Group 1
Product 1
Row 1 | 1 | 1 | 1 | 1 |
Row 2 | 1 | 1 | 1 | 1 |
Row 3 | 2 | 2 | 2 | 1 |
Row 4 | 2 | 2 | 1 | 1 |
   [Footer]   | 4 | 4 | 3 | 2 |
Product 2
Row 1 | 1 | 1 | 1 | 1 |
Row 2 | 1 | 1 | 1 | 1 |
Row 3 | 2 | 2 | 2 | 1 |
Row 4 | 2 | 2 | 1 | 1 |
   [Footer]   | 4 | 4 | 3 | 2 |
[Footer]      | 8 | 8 | 6 | 4 |

I have it set up so each product's footer calculates the individual product's footer correctly, but not the top most group footer (the product grouping), it only calculates the last individual product's total as in the screenshot I attached. I'm not quite sure how to grab the totals from previous footers of the same grouping.

Here is my custom aggregate function as is now:

Protected Sub RadGrid1_CustomAggregate(ByVal sender As Object, ByVal e As GridCustomAggregateEventArgs) Handles RadGrid1.CustomAggregate

If e.Column.UniqueName = "Row" Then

e.Result = ""

Else

Dim length As Integer = RadGrid1.MasterTableView.GetItems(GridItemType.GroupHeader).Length

For i As Integer = 0 To length - 1

Dim total As Double = 0

Dim groupHeader As GridGroupHeaderItem = DirectCast(RadGrid1.MasterTableView.GetItems(GridItemType.GroupHeader)(i), GridGroupHeaderItem)

Dim children As GridItem() = groupHeader.GetChildItems()

For Each child As GridItem In children

If TypeOf child Is GridDataItem Then

Dim childItem As GridDataItem = TryCast(child, GridDataItem)

Dim rowText As String = childItem.Item("Row").Text

If rowText = "Row3" OrElse rowText = "Row4" Then

total += childItem.Item("Value").Text

End If

Next

e.Result = total

Next

End If

End Sub

Sorry if this is a dumb question, but I'm a little stuck here.

differences in running through pagelifecycle

Hi,

actually I'm looking for a method for loading data in a control with most minimal action on the server. (Means, when possible, only the control that needs to be refreshed should go through its lifecycle, not the rest of the pages controls).

I found some Information that it should be possible to handle this problem with RadXMLHttpPanel, but no exact information how to ensure that only the refreshed control goes through its lifecycle.

Any hints ?

As additional Information: We have a page that is build by WebParts encapsulating usercontrols. Our need ist to force single webparts/usercontrols to refresh by button/timer etc.
