I have a RadGrid setup so that double clicking a row opens a form under the row to allow editing. The form itself lives in a web user control.

On this form one of the fields is a CheckBox. It looks like this.

 
The code in the 'Checked=' bit sees that on edit the Checked property gets set to True or False. Perfect.

However, when I hit the Add New Record button, this line gets a problem.

Specified cast is not valid.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidCastException: Specified cast is not valid.

Source Error:

Line 24: <tr> Line 25: <td align="right">Active:</td> Line 26: <td><asp:CheckBox ID="chkIsActive" runat="server" Checked='<%# DataBinder.Eval( Container, "DataItem.con_Is_Active") %>' /></td> Line 27: <td></td> Line 28: <td></td>

Source File: c:\Dev\RadGrid\RadGrid\Controls\ContactDetails.ascx    Line: 26


It's pretty easy to understand why.  DataItem.con_Is_Active has no value on an Add New Record insert.

My question is, were do I intercept this to prevent this error on Adding a new Record?

I've looked for but have been unable to find the InitInsertButtons click event if any such event exists..

I'm sure this is simple I just don't know where to put such a check.  I suppose what I'd like to do is set the  DataItem.con_Is_Active property some default value (like 'False') before the it gets to this point.

The splitter is similar to the webmail demo (fulscreen)

However when the page loads you can clearly see the splitter be small, then "POP" into fullscreen. 

Is there any way around that??  at least somehow set a default height so the popping isn't so in your face.

Hi,

I was wondering how can I get the index of row in the UpdateCommand events of a TreeList. In a RadGrid, it would be like this :


But if doesn't work with a treeList. In fact, the proprety e.Item.ItemIndex doesn't seem to exist. So, I look around to found something, but I had no luck. So, may someone tell me how to retrieve the index of the selected row via a updateCommand.

Thank you

I tried following to export to pdf in Landscape page orientation:

 

RadGridResult.ExportSettings.Pdf.PageHeight = Unit.Parse("215mm")

 

RadGridResult.ExportSettings.Pdf.PageWidth = Unit.Parse("260mm");

But it didn't work, and I have no idea on how to export to Word in Landscape orientation.
But I can do it with Excel just fine. Is there anyway to "convert" Excel to PDF or Word format on the fly?

THanks

LamK.

 

 

 

 

By default, when we export from RadGrid to  MS Word, it automatically has 1 inches page margin, I would like to programmatically change it to 0.5.

Would you please show me how to do that?

Thanks

I have a Radgrid on an ASP.NET form and it is bound to a database table. In the view mode one of the columns has a text value in it that shows a mode. I am using an edit form. In the edit form I have a dropdown on that same field that allows the user to select one of three choices. I can find the dropdown in the edit template using

If TypeOf e.Item Is GridEditFormItem And e.Item.IsInEditMode Then
            dp = e.Item.FindControl("dpRoles")

But what I can't figure how to get is the current data value in the current data row. I know it is in the griddataitem but how do I get to this in the itemdatabound event. I want to "jam" the dropdown list to what is currently in the grid before it goes to edit mode on that row.

Thanks in advance for your help.

I have and email sent to a customer upon update with a URL of the ID that gets created.  If they click the URL it should take them directly to the radgrid with the open edititemformtemplate with all of it filled out.  Any ideas on how to accomplish this?

i have a rad Filter like below. i want to switch out the Display Name based on a condition.

<

 

 

telerik:RadFilter ID="WorkOrdersRadFilter" runat="server" Skin="WebBlue" ShowApplyButton="true"

 

 

 

OnApplyExpressions="WorkOrdersRadFilter_Apply" ApplyButtonText="Filter Work Orders"

 

 

 

OnPreRender="RadFilter_PreRender" OnFieldEditorCreating="RadFilter_FieldEditorCreating"

 

 

 

 

 

OnFieldEditorCreated

 

 

="RadFilter_FieldEditorCreated"

 

 

>
<FieldEditors>

 

 

 

<telerik:RadFilterTextFieldEditor FieldName="WORKORDERNUMBER" DisplayName="Work Order#"

 

 

 

DataType="System.String" />

 

 

 

 

<

 

 

goldcustom:RadFilterComboBoxEditor FieldName="WOTYPENAME" DisplayName="WO Type"

 

 

 

 

 

 

 

DataTextField="WOTYPENAME" DataSourceID="WorkOrderTypeFilterODS" DataType="System.String"

 

 

 

 

 

 

 

ComboBoxSkin="WebBlue" />

 

 

 

 

<

 

 

telerik:RadFilterTextFieldEditor FieldName="TRACKINGNUMBER" DisplayName="Tracking#"

 

 

 

DataType="System.String" />

 

 

 

<telerik:RadFilterTextFieldEditor FieldName="KEYREFERENCE" DisplayName="Key Ref"

 

 

 

DataType="System.String" />

 

</FieldEditors>

 

 

 

</telerik:RadFilter>
i tried what was suggested in one of the tutorials, but it never seems to fire this event.i also tried OnFieldEditorCreating which simply is used to invoke the class for radComboBoxes and that never fires either unless of course it's a radComboBox.
i assume that i want to do this when i click the "Add Expression" button on the RadFilter. is there some way i can switch out the DisplayName?? i've been thru every tutorial i can find, but nothing really works.
can i get some direct help? i'm a registered developer, do you guys need any info from me?
thanks

Want to run something like this to switch out the Display name depending on a condition:

 

protected void RadFilter_FieldEditorCreated(object sender, RadFilterFieldEditorCreatedEventArgs e)

{

    if (e.Editor.FieldName == "WORKORDERNUMBER")

    {

        e.Editor.DisplayName = "My custom text";

    }

}

I created a RadGrid and have a image button as a column; when I click image button, I need to open a new window with some existing page, passing some value.

Here's what I did. Please help:
1. created a RadGrid with OnItemCommand="RadGrid1_ItemCommand; and created a image button.

                <telerik:GridTemplateColumn AllowFiltering="false">
                    <ItemTemplate>
                        <asp:ImageButton ID="imgbtnEdit" ToolTip="Edit Solution" CommandName="modify" 
                            CommandArgument='<%# Bind("solution_id") %>' runat="server" ImageUrl="~/Images/edit.gif" />
                    </ItemTemplate>
                    <ItemStyle HorizontalAlign="Center" Width="2%"></ItemStyle>
                    <ItemStyle BorderStyle="Solid" HorizontalAlign="Left" VerticalAlign="Top" Width="1%" />

2.created .js file with following code
      function EditSolution(SolutionID)
      {
          var newWindow;
          var WindowName;
          WindowName = strSessionID + "EditSolution" + SolutionID;
          newWindow = window.open(
         strPublicMap + "/" + strDispLangCode + "/solutions/processsolution.asp?command=edit&solutionID=" + SolutionID,
         WindowName,
         "toolbar=yes,channelmode=no,menubar=yes,location=yes,directories=no,scrollbars=yes,resizable=yes,status=yes,height=470,width=750,left=1,top=1");
      }

 3. reference in .aspx file
<head id="Head1" runat="server">
    <title></title>
    <script language ="javascript"  type="text/javascript" src ="../Script/Home.js"></script> 
</head>

4. in code behind file

    Protected Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As GridCommandEventArgs) Handles RadGrid1.ItemCommand

        Dim strCommandName As String = e.CommandName.ToLower()
        Dim sTitle As String = ""
        Dim intIndex As Integer

        If (strCommandName = "browse" Or strCommandName = "modify" Or strCommandName = "attachment") Then
            intIndex = Convert.ToInt32(e.CommandArgument)
            Select Case strCommandName
                Case "modify"
                    EditSolution(intIndex)
                Case "attachment"
            End Select
        End If

Protected Sub EditSolution(ByVal iSolutionID As Integer)
        Dim strScript As String = String.Empty

        strScript = "javascript:EditSolution(" & iSolutionID & ");"
        ScriptManager.RegisterStartupScript(Me.RadGrid1, Me.GetType, "OpenAttachments", strScript, True)
End Sub

The js file should be fine since it is used by production. I just start to use telerik grid. I believe last line code is wrong, but not sure how to fix it.         ScriptManager.RegisterStartupScript(Me.RadGrid1, Me.GetType, "OpenAttachments", strScript, True)
Thanks in advance!
 

I am calling the RadAlert function in my code behind when a user clicks on the "Login" button. This is a very simple page with very simple functionality and I am following the examples to a tee, but still nothing. I am thinking it is because I am calling the function within a catch block when the login is unsuccessful, meaning that I am trying to display the window when the execution isn't finished. Can someone help me with this as I am stumped as to how best to proceed? My HTML and C# code is below:
