Hello all,

I am trying to get an event back to the server for deleting.  I have added a GridClientDeleteColumn to my radgrid.  Then I  added OnItemCommand, OnDeleteCommand, OnItemDeleted event handlers, but I am not getting any of these events when the delete is completed.

A work around that I found was using a GridButtonColumn and adding the confirm text to that, but the problem is that I wanted to have an image show for the delete and the GridButtonColumn doesn't seem  to be working with the ImageUrl property set.  Has anyone seen this before?

I would really appreciate it if someone could give me a resolution to either of these problems:

1) Why I can't get the server side event from the GridClientDeleteColumn?
2) Why the GridButtonColumn is not showing my image from the ImageUrl property?

Configuration:
ASP.NET 3.5
VS2008
Telerik.Web.UI.dll 2008.2.826.35

Thanks in advance,
Lee

I want to add a checkbox list to the details area of a radgrid.   Is there any telerik control that makes this easier, or do a just make a template and user the microsoft checkboxlist control?

hi Telerik
I am trying to open a rad window by selecting an option in the context menu that should be displayed on the right click of rad grid row. I tried opening rad window from code behind but it didnt worked so tried opening it from javascript. What is happening that it didnt show for the first time when i right click the context menu item. However it opens after every next click.Also i m passing the title and id  from the grid to the window,i obsered that it shows the title of the previous clicked row and not the current row on show.
here is the code behind:

protected void RadMenu1_ItemClick(object sender, RadMenuEventArgs e)

{

int radGridClickedRowIndex;

Label labeltitle;

radGridClickedRowIndex =

Convert.ToInt32(Request.Form["radGridClickedRowIndex"]);

string SignpostId= RadGrid1.Items[radGridClickedRowIndex].Cells[4].Text;

GridDataItem current =RadGrid1.Items[radGridClickedRowIndex];

labeltitle = (

Label)current["Ref"].FindControl("Label4");

string STitle = labeltitle.Text;

if (e.Item.Text == "Add Criteria")

{

string arg1 = "AwardId=" + ParentPage.iaward_id;

string arg2 = "&SignpostId=" + SignpostId;

string arg3 = "&STitle=" + STitle;

e.Item.Attributes[

"onclick"] = "return AddCriteria('" + arg1 + "','" + arg2 + "','" + arg3 + "')";

}

if (e.Item.Text == "Edit Criteria")

{

string arg1 = "AwardId=" + ParentPage.iaward_id;

string arg2 = "&SignpostId=" + SignpostId;

string arg3 = "&STitle=" + STitle;

e.Item.Attributes[

"onclick"] = "EditCriteria('" + arg1 + "','" + arg2 + "','" + arg3 + "')";

 }
}

Kindly help on how to open rad window on the click of context menu by passing paramaters to the rad window. I am new to teleik and have tried all combinations that i know. 
Also wanted to share that i am able to open the rad window from code behind on the rad tree view context menu click. The code behind for the code its working fine in tree view is :

protected void ContextClicked(object sender, RadTreeViewContextMenuEventArgs e)

{

string s = String.Format("You clicked the <b>'{0}'</b> context item for node <b>'{1}'</b>", e.Node.ContextMenuID, e.Node.Text);

string sSelectedText = e.MenuItem.Text;

ParentPage.GeneralFunctions.AssignLabelText(Page.Controls,

"StatusText", s);

ViewUnitsPanel.Visible =

false;

 if (sSelectedText == "Add Units")

{

string arg1 = "AwardBodyId=" + ParentPage.iawardbody_id + "&GroupId= " + e.Node.Value + "&Title= " + e.Node.Text + "&Action=Add";

Telerik.Web.UI.

RadWindow newwindow = new Telerik.Web.UI.RadWindow();

newwindow.ID = "SearchWnd";

newwindow.VisibleOnPageLoad = true;

newwindow.Width = 1100;

newwindow.Height = 800;

newwindow.NavigateUrl = "~/custom/cmatters/learningportal/awards/GroupUnits.aspx?" + arg1;

RadWindowManager1.Windows.Add(newwindow);

ViewUnitsPanel.Visible =

true;

}

.}

 However when i use the above code to open window on the context click of  rad grid from code behind nothing happens. The ASP.Net version is 2.0 and Telerik version is :RadControls for ASPNET AJAX Q1 2008

Kindly help.Many thanks.

Hi everyone, I have a webpage includes RadGrid and it has several columns, one of the column shows us the member's e-mail addresses, and each row has a hyperlink attribute ( to send instant mail with outlook or etc.) But All RadGrid also exportable with Excel. Here is a little bit problem, because when I want to use Hyperlink attribute to link outlook I've to change the type of the column,
and it can't appear in the exported file, other columns has not such a problem, they appears stably.

The Normal columns uses : <radG:GridBoundColumn DataField="E_MAIL">
Hyperlinked Columns uses : <radG:GridHyperLinkColumn DataNavigateUrlFields="E_MAIL"> 

So How can I show the E MAIL columns when I export to Excel ?

HyperLinked Code :

<

radG:GridHyperLinkColumn DataNavigateUrlFields="E_MAIL" UniqueName="E_MAIL" DataTextField="E_MAIL" DataNavigateUrlFormatString="mailto:{0}" DataTextFormatString="{0}"
ItemStyle-Width="100px" ItemStyle-Font-Underline="true" HeaderText="E-Mail" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center">
</radG:GridHyperLinkColumn>

 

I want to use the drag and drop feature of radgrid to drag from a radgrid and drop it in an aspx form. Are there any examples or demos?

Hi

I am using Telerik controls 2008 Q2 SP2.

When a RadDatePicker or RadTimeView is near the bottom of the page the popup always shows past the bottom of the page. This means that the user has to scroll down to select anything.

I noticed that the RadCombo is intelligent enough to detect the bottom of the page and show the popup above the control.

Is there a way of doing this with the RadDatePicker and RadTimeView?


Kind regards

Hello,

I would like to use the example here:
http://demos.telerik.com/ASPNET/Prometheus/Slider/Examples/Skinning/DefaultCS.aspx

But, I want the slider to perform like a thermometer where the value at the top of the slider is 100 and the value at the bottom is 0.  Is this easily done?

Thanks.

Hi all,

May any one help me to(wpf windowsapplication)
Remove child record from radgridview(AutoGeneratedHiearchy) based on selection of parent record .I used Tabledefination  to add childtable to radgridview.

I will be thankfull to you if u send response as soon as possible.

I was looking at this link:

http://www.telerik.com/help/aspnet-ajax/grdexport.html

and I don't see the ExcelExportCellFormatting event.  I need to make sure a certain column gets exported as text rather than a number.

Also, can I exclude some columns from being exported?
