<DetailTables>

<telerik:GridTableView HierarchyLoadMode="Client" DataSourceID="LinqDataSource2" DataKeyNames="ID"

Width="100%" runat="server" CommandItemDisplay="Bottom" AllowAutomaticDeletes="true"

AllowFilteringByColumn="false" Name="Detractions">

<ParentTableRelation>

<telerik:GridRelationFields MasterKeyField="ID" DetailKeyField="ExaminationID" />

</ParentTableRelation>

<EditFormSettings>

<PopUpSettings ScrollBars="None"></PopUpSettings>

Hi Rahul,

Try accessing the LinkButton in the CommandItemTemplate as shown below.

CS:
protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e) 
     { 
         if ((e.Item is GridCommandItem) && (e.Item.OwnerTableView.Name == "Detractions")) 
         { 
             GridCommandItem cmditm = (GridCommandItem)e.Item; 
             LinkButton lnkbtn = (LinkButton)cmditm.FindControl("lnkAddDetraction"); 
             
         } 
    } 
         

Hope this helps..
Shinu.

Hi Rahul,

If you would like to modify settings for the link button inside the detail table's command item, the proper place to do that are the ItemCreated or ItemDataBound events of the grid. This will ensure that the viewstate and the event lifecycle of the link button will be consistent.

More information about the ItemCreated/ItemDataBound events of RadGrid you can gather from this resource:

Hi Rahul,

Try setting the EventHandler for the ItemDataBound event in the aspx as shown below.

ASPX:
 <telerik:RadGrid ID="RadGrid1" runat="server"  OnItemDataBound="RadGrid1_ItemDataBound"  OnDetailTableDataBind="RadGrid1_DetailTableDataBind" > 


Thanks
Princy.

Hi,
My problem of opening rad window on click on link button of grid have solved.
Thanks alot for all your help,


I have used this code in item data bound 

protected void grdExams_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

if

((e.Item is GridCommandItem) && (e.Item.OwnerTableView.Name == "Detractions"))

{

GridCommandItem cmditm = (GridCommandItem)e.Item;

LinkButton lnkbtn = (LinkButton)cmditm.FindControl("lnkAddDetraction");

lnkbtn.OnClientClick =

"window.radopen('Detractions/Edit.aspx','DetractionDialog');return false;";

}

}

But now on telerik pop up i am using edit.aspx page.
in this page i am using 

<radT:RadTreeView ID="tvDetractionTypes" runat="server" DataTextField="Title" DataFieldID="ID"

BeforeClientClick="handleNodeClick" DataValueField="ID" DataFieldParentID="ParentDetractionTypeID"

Skin="Office2007" DataSourceID="dsDetractionTypes" Height="150px" Width="250px"

OnNodeBound="tvDetractionTypes_NodeBound">

</radT:RadTreeView>

and in java script 

<

<script type="text/javascript">

 

function

handleNodeClick(node)

{

//if this is a parent node, expand it and select the first child

 

if (node.Parent == null && node.Nodes.length > 0)

{

node.Expand();

node.TreeView.UnSelectAllNodes();

node.Nodes[0].Select();

return false;

}

// Unlock any locked sliders

 

SliderArrays[0][idxSliderLocked] =

false;

SliderArrays[1][idxSliderLocked] =

false;

SliderArrays[2][idxSliderLocked] =

false;

SliderArrays[3][idxSliderLocked] =

false;

// Make sliders visible

 

SliderArrays[0][idxSliderDisplay] =

true;

SliderArrays[1][idxSliderDisplay] =

true;

SliderArrays[2][idxSliderDisplay] =

true;

SliderArrays[3][idxSliderDisplay] =

true;

// Redraw the sliders to reflect the new default values

 

SliderArrays[0][idxSliderDisplayWeight] = node.Attributes[

"DefaultTech"];

SliderArrays[1][idxSliderDisplayWeight] = node.Attributes[

"DefaultEquip"];

SliderArrays[2][idxSliderDisplayWeight] = node.Attributes[

"DefaultPatient"];

SliderArrays[3][idxSliderDisplayWeight] = node.Attributes[

"DefaultProcess"];

SliderDrawTable();

// Change the default DV

 

var combo = <%= RecursiveFindControl("cboSeverity").ClientID %>;

var item = combo.FindItemByValue(node.Attributes["DefaultDV"]);

if (item != null) item.Select();

//Change the tooltip text

 

<%= RecursiveFindControl(

"lnkTip").ClientID %>.title = node.Attributes["ChangeTip"];

return true;

}

</script>

Its giving run time error in the below line "exception is thrown"

<%= RecursiveFindControl("lnkTip").ClientID %>.title = node.Attributes["ChangeTip"];


if i removed the javascript and comment the <radT:RadTreeView it gives runtime error

Cannot find a string resource with key 'ImageEditor' in App_GlobalResources/RadEditor.Tools.resx. Please, make sure that your custom localization has all needed resource strings, or copy the original localization resources from your installation folder to App_GlobalResources.

please assist
