The Excel-Like Radgrid code that given by telerik is very useful. I am using the code excellikegrid-updated.zip in my application. It is working fine for the first set of records.

I am using virtual paging in that Excel-like RadGrid solution. For first page, the records displaying as like excel editable mode and we are able to add/Update data in those cells. But when we go to second page using pagination it throws an exception follows.
"Specified argument was out of the range of valid values.
Parameter name: index".

at the line "TextBox textBox = (item[column.UniqueName].Controls[0]) as TextBox;" Inside pre-render event of RadGrid.

At the first time(page load), After "Need Datasource" event, the event "Data Binding" firing and sets all the records in the grid to edit mode.

protected void radGridProducts_DataBinding(object sender, EventArgs e)

{

DataTable currentProducts = _presenter.GetCurrentDataTable();

for (int i = 0; i < currentProducts.Rows.Count; i++)

//for (int i = 0; i < radGridProducts.VirtualItemCount; i++)

{

radGridProducts.EditIndexes.Add(i);

}

At the time of postback for Next page, after the event "Need Datasource", the "radGridProducts_DataBinding" event is not firing and it goes to pre-render event; no controls in any item of grig and displays the above error message.

I have tried to set all grid items to editable mode in pre-render event iteself as follows.

protected void radGridProducts_PreRender(object sender, EventArgs e)

{

//Added for Test purpose

DataTable currentProducts = _presenter.GetCurrentDataTable();

for (int i = 0; i < currentProducts.Rows.Count; i++)

{

radGridProducts.EditIndexes.Add(i);

} //Added for Test purpose

radGridProducts.Attributes.Add("onkeydown", "onKeyDown(this,event);");

int itemsCount = 0;

int columnsCount = 0;

StringBuilder builder = new StringBuilder();

// Attach the event handlers to the client side events of the TextBoxes.

foreach (GridDataItem item in radGridProducts.MasterTableView.Items)

{

if (item is GridDataItem)

{

columnsCount = 0;

for (int i = 2; i < radGridProducts.MasterTableView.RenderColumns.Length; i++)

{

GridColumn column = radGridProducts.MasterTableView.RenderColumns[i];

//if (item[column.UniqueName].Controls.Count != 0)

//{

TextBox textBox = (item[column.UniqueName].Controls[0]) as TextBox;

if (textBox != null)

{

textBox.Attributes.Add("ondblclick", "cellDoubleClickFunction('" + textBox.ClientID + "');");

textBox.Attributes.Add("onclick", "cellClick('" + textBox.ClientID + "');");

}

if (i == 2 && !string.IsNullOrEmpty(textBox.Text))

{

textBox.ReadOnly = true;

textBox.Attributes.Add("class", "readOnly");

}

//}

columnsCount++;

}

itemsCount++;

}

RadScriptManager.RegisterStartupScript(Page, Page.GetType(), "init", "colls = " + columnsCount + ";rows=" + itemsCount + ";", true);

}

But still, it throws the same "Index out of bound" exception while getting the TextBox control.

Any solution for this Issue?
Thanks in Advance.

force refresh on control in master page

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" />

<telerik:RadAjaxManagerProxy ID="AjaxManagerProxy1" runat="server" >

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadGrid1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />

<telerik:AjaxUpdatedControl ControlID="txtSelectedValues" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

So I have the following setting in a user control. Now in a master page, I have this control and another control (say control 2). What I want is to update control 2 when the user control get a select index change event. I can fire the event and set the control 2 but it does not refresh cause it is not listed in the updatedcontrol. So my question is.
1) can controls from a master page be added to a list of updated controls in the user control. If so, how
2) Is there a way to force the update (override the ajax setting) in the master page so that it recognizes the refresh of control 2.

Thanks for any help, suggestions.

FIX: Control skins are not applied if RadStyleSheetManager is used when the page does not have a head tag (Q2 2010 SP2)

Problem: The latest Q2 2010 SP2 release greatly improves RadStyleSheetManager and it now combines style sheets registered after AJAX updates. By implementing this functionality we inadvertently broke the scenario when your page does not have a <head> element. Now all style sheets registered with RSSM fail to load if this element is missing.

Solution: The problem will be fixed in the next internal build (version 2010.2.1001+).

Workaround: Add a <head runat="server"> tag to your page.

Grid row color

Hi ,
I am using telerik rad grid in my Application .The main motive for using the radgrid is to implement the drag and drop row functionality , which is working great . My issue is i have given different colors to the rows on the grids item data bound event based on some conditions , so when i select a row the color i have given to the row is over ridden by the default color of grid(when we select a row). That breaks my design because the new color doesn't completely overlaps the row it , i will attach a screen shot so that u can see( it looks very odd) . in screen shot the row color red which i have given is not completely over lapped by the default color of row select .

Either it must completely over lap or the color should not change . please advise
