Is there an easy way to get the entire collection of items after a user goes to another page of the gird? Or, do I have to iterate through the Databound items and make my own collection? Thanks

Disable Node Click On Server Side For Parent Nodes

You Can Disable Node Click On Parent Node On Server Side By Setting the Value of PostBack to false then handle the level for node on node click event

Example :

RadTreeNode Node = new RadTreeNode(Node Name Here, Node Value Here)

Node.PostBack = false;

tree.Nodes.Add(Node );

//And on NodeClick Event We Do The Following :

protected void tree_NodeClick(object sender, RadTreeNodeEventArgs e)

{

    if (e.Node.Level != 0)

    {

       //Your Event For Click Here

    }

}

[Solved] Can't enable column resizing in RadGrid

Hi,
I want to use RadControls to maintain some of my data. First, I am testing its fuctionality to see if it can do all I need to. I created a Web Application with a RadGrid as the major element. Everything works fine in the RadGrid except for column resizing. I am able to import my data from SQL Server and reorder the columns and filter/sort and all that good stuff. However, as hard as I try, I cannot seem to make the columns resizable. I tried copying the code in html as well as C# into their appropriate files, but it just isn't working. I don't know why. If someone could help me with this problem, it would be much appreciated. Thank you.

AjaxLoadingPanel writes updatedcontrolID

Hi,
I am using AjaxLoadingPanel with a farpoint control. Since, it was not showing the loading image, I tried to put the farpoint control inside a panel or div. Code below shows how I have implemented the loading panel.

<

telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Height="75px"

Width="75px">

<img alt="Loading..." src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading.gif") %>'

style="border: 0px;" />

</telerik:RadAjaxLoadingPanel>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<telerik:AjaxSetting AjaxControlID="ButtonViewColumnHeader">

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

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

After loading the control, I get the clientID of the updated control written on my aspx page (just above the control) as shown below.

175782|updatePanel|ctl00_MasterContentPlaceHolder_ctl00_MasterContentPlaceHolder_divSpreadPanel|

Has anyone come across such a strange issue? Is there any way to get rid of this display?

many thanks,

Anu

Empty space above scrollbar

Hi,
When i use radgrid with a headertemplate with scrolling, then i get empty spcae above the scrollbar (so not in sync with the styles). It happens only with firefox and its due to style "margin-right: 13px" in the header <div>.

Can you tell me is there any property that i can set, or any fix for it?

My radgrid structure (if its of any help to you)

<radgrid>
<ClientSettings>
     <MasterTableView>
        <CommandItemTemplate>
            <Columns>
                 <GridClientSelectColumn>
                     <HeaderTemplate>
                     <ItemTemplate>

regards,
Naresh

                        category.SelectedValue = col.ToString();// parent.DataSetIndex; 
        
                        //category.Text = parent["TeamCategoryID"].Text; 
        
                    } 
        
                }

How to get the number of rows, column and selected items

I have a radgrid and i want to know the following

1. number of rows
2. number of columns
3. row of the item selected in grid
4. column of the item selected in grid

I have tried grid.column.count but it does not have that property?

Additional question:

I have a checkbox in the grid and i want the user to select only one checkbox...

i need to deselect the previous selected checkbox if the user will check another checkbox.

Is it possible to just find the column of the checkbox then uncheck all in the checkbox in the event "onmousedown"

since if its not possible im thinking to make a "for loop" and locate each cell for the checkbox.

Dynamic Java script errors on RadGrid Rowselect

Hi,

I have radGrid with the following markup:

<

telerik:RadGrid ID="RadGridMapFilter" runat="server" AllowPaging="True" ClientSettings-EnablePostBackOnRowClick="true"

PagerStyle-Mode="Slider"

GridLines="None" Width="377px" AutoGenerateColumns="False" Height="320px" >

<telerik:GridBoundColumn DataField="FilterAbb" HeaderText="Filters"

SortExpression="Filters" Visible="false" />

<telerik:GridBoundColumn DataField="FilterName" HeaderText="Filters"

SortExpression="Filters" Visible="true" />

</columns>

</RowIndicatorColumn>

</ExpandCollapseColumn>

</EditFormSettings>

</MasterTableView>

</ClientSettings>

</telerik:RadGrid>

The issue is that When I select a row in this grid, randomly it will spit out Dynamic javascript errors. After debugging the Dynamic javascript error it breaks on the first line(var _33 =_31.parentNode;)

var _33=_31.parentNode;
var _34=_31.nextSibling||Telerik.Web.UI.RadAjaxControl.GetNodeNextSibling(_31);
Telerik.Web.UI.RadAjaxControl.InsertAtLocation(_32,_33,_34);
_31.parentNode.removeChild(_31);
}

The error just says "Microsoft JScript runtime error: Object required"

Any idea why this happens randomly.The version of the telerik.web.UI dll we are using is v2008.2.1001.35.

Please let me know if you need more information from me.

Thank you,
Anshul.
