So I have a very simple RadGrid (no heirarchy) and a very simple RadTreeView. I followed the code example in one of the demos I cannot seem to find now. But here are the oddities in my situation:

1. Everything about the RadTreeView seems to work just fine.
2. The RadGrid Columns are created programtically whilst the rest of the radGrad is done design time.
3. Eight of the thirteen or so columns are GridTemplateColumns.

The page keeps giving me an error after the page has rendered in the browser when it tries to seemingly instantiate this simple custom remove link. The error comes in the line here and caused by the fact that cItem.DataItem has a null value. Keep in mind the code has passed through the same code path twice already (prior to the rendering) and it is not until this third time (post-render) that the cItem.DateItem is set to nul. Another interesting note, the KeyValues remains unchanged ( KeyValues "{BuildGuid:\"7278f75e-4712-8f38-c598-b9a144c2a9fc\"}" string) in all three passes through the code path during the life cycle of the page.

Here is the entire template object:

public partial class BuildRemoveLinkButton : ITemplate

{

protected LinkButton Link;

private string ColumnName;

public BuildRemoveLinkButton(string ColumnNameInput)

{

this.ColumnName = ColumnNameInput;

}

public void InstantiateIn(Control container)

{

GridDataItem cItem = container.Parent as GridDataItem;

if (cItem != null)

{

Link = new LinkButton();

Link.Text = "remove";

Link.ToolTip = "Remove this build from the view";

Link.CommandArgument = (string)((DataRowView)cItem.DataItem)["BuildGuid"].ToString();

Link.ID = String.Format("Remove-{0}", this.ColumnName);

Link.CommandName = ColumnName;

container.Controls.Add(Link);

}

}

}

Just to remind you, the page and RadGrid have already rendered in the browser. Here is the RadGrid defintion:

Here also is the column creation code which is called during Page_Init:

Finally, here is the call stack causeing the error after the page has rendered...

 Any help/insights someone may have will be greatly appreciated.

My page :

Click toolbar button , I use client script to  open the window first.  The button's postback is true, then on server side ,get data from database to update the detail panel.  The Code works well.
But the FormDecorator can  not apply to the textbox correctly. (see the attached file)

if I open the window by sending the  javascript to client after update the detail panel on server side, the textbox display correctly.
but this is not I want , because I want the user can see the loading procedure.

any suggestion?

Hi

Changing the width of the Hyperlink Manager / LinkManager.ascx, has no effect.

radEditor.DialogOpener.Width = new Unit(450, UnitType.Pixel);

or

radEditor.DialogOpener.Window.Width = new Unit(450, UnitType.Pixel);

The LinkManager.ascx is customized

Is it possible to change the width ?

Hi All

I am using Radeditor for one of my applications. I have added toolbar item to radeditor. But the issue is the realfontsize shows only font size in pixels. Is there a way around to get the font size in points.

Any help will be much appreciated.

Thanks

I have a radgrid which gets bound to a dataset returned by a stored procedure. I have 3 hyperlink 'options' that gets generated dynamically from the DB. Instead of creating 3 columns with links, I just wanted a dropdownlist that users can select from and a button that will trigger the redirect to a page referenced by the links.

Also, I added the button on the template column but can't get it to display , I'll just create an image button then on another template column. But on the on-click event, when I do a findcontrol, I can't seem to see the radcombobox so I can reference the selected value and redirect the user to the link. Please advise. Code samples would help. Thanks!

I have code similar to below:

 

 

<telerik:GridTemplateColumn HeaderText="Options" UniqueName="Options">

 

 

 

<ItemTemplate>

 

 

 

<telerik:RadComboBox ID="rcbOptions" runat="server" AllowCustomText="True"

 

 

 

HighlightTemplatedItems="True" EmptyMessage="(Select)">

 

 

 

<Items>

 

 

 

<telerik:RadComboBoxItem Text="Option1" Value='<%#Eval("URL1") %>' />

 

 

 

<telerik:RadComboBoxItem Text="Option2" Value='<%#Eval("URL2") %>' />

 

 

 

<telerik:RadComboBoxItem Text="Option3" Value='<%#Eval("URL3") %>' />

 

 

 

</Items>

 

 

 

</telerik:RadComboBox>

 

 

 

</ItemTemplate>

 

 

 

</telerik:GridTemplateColumn>

 

I need to select the date from RadDatepicker in single click. But now I need to double click to select the date. Could you please help me to fix this issue ?

Thanks

Dears,

I am using RadTree in my web page, I want to ask a user before moving from selected node to another
"Do you want to save changes?"  and give hime the following button options: Yes, No, and Cancel. Becuase javascript confirm has only Ok and cancel button, I used radconfirm and change the template as the following:

 

<ConfirmTemplate>

 

 

<div style="text-align: center">

 

{1}

 

<br />

 

 

<br />

 

 

<input id="btnYes" type="button" value="Yes" onclick="$find('{0}').close(true);" />

 

 

<input id="btnNo" type="button" value="No" onclick="$find('{0}').close(false);" />

 

 

<input id="btnCancel" type="button" value="Cancel" onclick="$find('{0}').close(null);" />

 

 

</div>

 

 

</ConfirmTemplate>

the radconfirm is ok, and it returns null when user click on "Cancel" button. but the problem is I have to call the radconfirm inside the treeview ClientNodeClicking event, and radconfirm has CallBackFunction, and in CallBackFunction I can not execute:

 

eventArgs.set_cancel(true);

becuase eventArgs is avilable only in ClientNodeClicking.
So, could you please help me in that.

I am trying to inherit GridBoundColumn.

where i override preparecell method.

I am putting an ImageButton  in GridDataItem.

now i need to fire owner grid ItemCommand event on this ImageButton's  Click event.

How can i do that?

check out this code.

[ToolboxData("<{0}:ActiveDeactiveColumn runat=server></{0}:ActiveDeactiveColumn>")]
    public class ActiveDeactiveColumn : GridBoundColumn
    {
        public override void PrepareCell(TableCell cell, GridItem item)
        {
          
            if (item is GridHeaderItem)
            {
                Literal lt = new Literal();

                lt.Text = this.HeaderText;

                cell.Controls.Add(lt);
            }

            if (item is GridDataItem)
            {

                ImageButton imgBtn = new ImageButton();

                bool value = (Boolean)DataBinder.Eval(item.DataItem, this.DataField);

                String url = value ? "OSS.Resources.tick.gif" : "OSS.Resources.cross.gif";

                imgBtn.ImageUrl = this.Owner.OwnerGrid.Page.ClientScript.GetWebResourceUrl(this.GetType(), url);

                imgBtn.OnClientClick = "return confirm('Are you sure want to " + (value ? "deactivate" : "activate") + " this record?')";

                imgBtn.CommandName = value ? "deactivate" : "activate";

                //What should be written Here?
                //imgBtn.Click += ""???
               // how can i bind this.owner.ownerGrid.ItemCommand (RadGrid.ItemCommand) event to this ImageButton event?
               
                cell.Controls.Add(imgBtn);
 
            }   

        }
    }

While I'm at it . . .

I have an edit form template which is nested in a panel bar.  I'm having trouble accessing the form objects in the template from the code behind.  Here is the panel bar/grid/template:

 

I've tried a dozen different ways of accessing txtInvoiceAmt, none with success.  The basis of my attempts is some form of:

 

Nothing seems to work.  Any ideas?

 

Thanks again.

I have developed a webpart in SharePoint Foundation 2010, and use RadGrid control in it. I have following codes:
Panel pnl = new Panel();

 

pnl.ID =

"Panel1";

 

pnl.Attributes.Add(

"style", "Overflow-x:auto");

 

pnl.Width = System.Web.UI.WebControls.Unit.Percentage(100);
pnl.Controls.Add(radGridInstance);
It runs well first. But after scrolling, UI RadGrid appears  a vertical line and no border in header.
I have no set skin of RadGrid.
I have a attached screenshot.
Thanks in advance.
