Questions on UI for ASP.NET AJAX Forum

Hi,

According to the documentation, OnColumnResizing should be passed a column index and a width
(http://www.telerik.com/help/aspnet-ajax/grid_oncolumnresizing.html)

However, the example provided uses sender and eventArgs, and the example demonstrates how to find the current width of the column, not the new value that should be assigned. How do I get the new width?

Thanks,
Brad

contextmenu and rowclick stops working on every other postback

I have created a usercontrol for the grid. I am having an issue where if you select a column to order by (click the heading), after the postbakc no rowclick, contextMenu and header contextMenu will work. However if you sort again, they do. So on every other postback the menu will work.

I have read on another forumk about adding the id of the contextMenu to the radajaxproxymanager, however the header contextMenu has no ID, also the rowclick also has no id as it is part of the grid. My code is below,

<telerik:RadAjaxPanel runat="server" ID="RadAjaxPanel1" LoadingPanelID="progressLoader">

<telerik:RadGrid ID="RadGrid1"

runat="server"

GridLines="Vertical"

AllowSorting="true"

Serialization of GridSettings

In our application, we gave user options to store the grid settings to user. We were using 2009 Q2 Telerik RADGrid. Now that we upgraded the RADGrid to Q3, the grid settings gives error. We soon figured out that may be GridSettings are not compatiable. The end user doesn't wish to lose the already stored settings. Is there any utility or code to covert the old settings to new settings compatiable to newer RADGrid?

AjaxPanel used with "legacy" mode

Our website needs to use:

<xhtmlConformance mode="Legacy" />

in the system.web section of our web config file.

I was not able to get the AjaxPanel to work when this is on. Setting it to "transitional" or "strict" cause the panel to work nicely. Unfortunately, changing this seetting at this time is not a choice for us. Is the another way to make this work?

Clarification in Hierarchical Excel Export

Dear Telerik,

I am having the RadGrid which is also having child details showing through hierarchical method of grid. I have the following doubts to Export the grid into Excel.

* Need to export the parent grid and hierarchical or child details only if it is expanded.
* I would like to show only the datas means columns and rows of parent and child rather than displaying the items like filter,expand/collapse, add/referesh/edit buttons etc.
* I used the follwing block of code to export excel. But it seems i am not not getting the proper positin of the columns means columns showing right side and rows are showing left side of the excel sheet. It is also exporting all of the child rows from the grid eventhough i am not expanding all of them.

private void ConfigureExcelExport()

{

//ExportExcel configuration settings

//rgPostingBill.MasterTableView.Caption = "PostingNotice Billing Report";

RadGrid1.ExportSettings.FileName = "PostingNotice";

RadGrid1.ExportSettings.IgnorePaging = true;

//RadGrid1.ExportSettings.HideStructureColumns = true;

RadGrid1.MasterTableView.HierarchyDefaultExpanded = true;

RadGrid1.ExportSettings.ExportOnlyData = true;

RadGrid1.ExportSettings.OpenInNewWindow = true;

}

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)

{

if (isExcelExport)

{

if (e.Item is GridNoRecordsItem)

e.Item.Visible = false;

if (e.Item is GridCommandItem)

e.Item.Visible = false;

//if (e.Item is GridNestedViewItem)

// e.Item.Cells[0].Visible = false;

//if (e.Item is GridDataItem)

//{

// GridDataItem item = e.Item as GridDataItem;

// foreach (GridColumn col in e.Item.OwnerTableView.RenderColumns)

// if (!(col is GridBoundColumn))

// item[col.UniqueName].Visible = false;

//}

}

Hope my above code and scenario is understandable.If so please let me know the possibilites.

-Thanks in Advance

can radgrid have more than 1 GridEditCommandColumn?

Hi,

Can radgrit have more than 1 GridEditCommandColumn?

I already have 1 GridEditCommandColumn where I would display a sub section when clicked. But I need another GridEditCommandColumn because I have to have another sub section to display.

So for my radGrid, the GridEditCommandColumn A will show section A, and GridEditCommandColumn B will show section B.

However, I get an error when I put two GridEditCommandColumn. Is there a work around for this?

Please see attached pic for the example scenario.
