Hi all!
I have a problem with the event CreateColumnEditor of a RadGrid. My code has to generate a Column Editor for the TextBox a different one for the ComboBox. The problem is that the event is fired even if I haven't pressed the edit button yet. I can assure it because I did debug it. This happens only when I add the part of code that follows:
 if (e.Column is GridDropDownColumn)......

Here there is the C# code:

protected void RadGrid_Processes_CreateColumnEditor(object sender, GridCreateColumnEditorEventArgs e)
{
    Unit width;
    String str;

    if (e.Column is GridBoundColumn)
    {
        width = e.Column.HeaderStyle.Width;
        str = (e.Column as GridBoundColumn).DataField;
        int indexEditing=0;
        bool even = true;
        
        switch (entityType)
        {
            case "COMP":

                if (str.Equals("Code"))
                {
                    e.ColumnEditor = new TextBoxColumnEditor(10, true, str, width, true, true, hfCodes.Value, even);
                }
                break;

            default:
                break;
        }
    }

    if (e.Column is GridDropDownColumn)
    {
        str = (e.Column as GridDropDownColumn).DataField;
        switch (entityType)
        {
            case "CTRL":
                if (str.Equals("FK_ControlType"))
                {
                    e.ColumnEditor = new DropDownColumnEditor(true, str, true);
                }
                break;

            default:
                break;
        }
    }
}

Here there is the ASP.NET code:

        <telerik:RadGrid ID="RadGrid_Processes" runat="server"
            AutoGenerateColumns="False" DataSourceID="LinqDataSource_Entities"
            oninit="RadGrid_Processes_Init"
            onitemcreated="RadGrid_Processes_ItemCreated" GridLines="None"
            onitemcommand="RadGrid_Processes_ItemCommand"
            onitemdatabound="RadGrid_Processes_ItemDataBound"
            onprerender="RadGrid_Processes_PreRender"
            onneeddatasource="RadGrid_Processes_NeedDataSource"
            ondatabinding="RadGrid_Processes_DataBinding" onload="RadGrid_Processes_Load"
            OnCreateColumnEditor="RadGrid_Processes_CreateColumnEditor"    >
            <SelectedItemStyle CssClass="rgAltRow" />
            <MasterTableView DataKeyNames="Id"
                    EditMode="InPlace" CommandItemDisplay="Bottom" InsertItemDisplay="Bottom" >
                <EditFormSettings>
                    <FormTableItemStyle HorizontalAlign="Left" />
                    <FormTableAlternatingItemStyle HorizontalAlign="Left"/>
                </EditFormSettings>
                <ItemStyle CssClass="rgRow" Font-Bold="False" Font-Italic="False" Font-Overline="False"
                    Font-Strikeout="False" Font-Underline="False" HorizontalAlign="Left"
                    Wrap="True" />
                <AlternatingItemStyle CssClass="rgAltRow" Font-Bold="False" Font-Italic="False"
                    Font-Overline="False" Font-Strikeout="False" Font-Underline="False"
                    HorizontalAlign="Left" Wrap="True" />
                <EditItemStyle Font-Bold="False" Font-Italic="False" Font-Overline="False"
                    Font-Strikeout="False" Font-Underline="False" HorizontalAlign="Left"
                    Wrap="True" />
            </MasterTableView>
    </telerik:RadGrid>


Thanks in advance.

Hi, all!

I have a Tabstrip with some tab. I have a contextmenu also what I use for the right click on each tab (RadContextMenu's

ContextMenuControlTarget ControlID

 

property). But at one tab I do not want to show the ContextMenu.
My problem is that in the TabStrip's OnClientContextMenu event I can not cancel the contextmenu to open and in the ContextMenu's OnClientShowing event I do not know which tab triggerd the event so I can not cancel the desired event.
Any suggestion?

Thanks.

I'm getting an error when I try to extend the RadTextBox using the ajax control toolkit PasswordStrength extender.

Is there any work-around already created for this?  Is this something that may be fixed in the future?

Extender control '' cannot extend 'txtPassword'. Extender controls of type 'AjaxControlToolkit.PasswordStrength' cannot extend controls of type 'Telerik.Web.UI.RadTextBox'.

Hi: Have you seen the NumericBox used by Microsoft Money 2007.
Its a good idea, it is a numeric box, when you press any operator key (+,-,*)
it drops down a calculator.

In my Source Code file i have a Hyperlink control... Which i want to access and give the url from code behind. I did using the following method but it is giving me error.
Please help me... Its very urgent.

The ScriptRegistrar.Render() method is throwing the exception: Specified file does not exist: "~/Scripts/jquery-1.4.js"

This is because I have upgraded to JQuery 1.4.1 .  What is my solution?

Hi,

Hello,

I might be missing something obvious here, but server-side validation (i.e. Page.IsValid) fails for all my RadTextBox items when javascript is disabled.

 

<asp:ValidationSummary id="valSummary" runat="server" DisplayMode="BulletList" ShowSummary="true" />

 

 

<label for="txtStudentFirstName">First Name</label>

 

 

<telerik:RadTextBox ID="txtStudentFirstName" runat="server" CssClass="RadTextBox" MaxLength="30" />

 

<asp:RequiredFieldValidator id="rfvStudentFirstName" runat="server" ControlToValidate="txtStudentFirstName" ErrorMessage="First Name is required" Display="None" />

It seems as though the input value is not getting passed through. Could someone please shed some light on this...

Many thanks for any response.

Hi,

I've a radgrid with scrolling enabled. I need to set the scroll height dynamically in he javascript in the onresize event.

how do i do this. I know scrolheight takes only pixels. I calculate my grid's height based on the formla:
(items.count * 24 ) + gridheaderheight.

Now the question is how can i access the scroll height in my javascript and set it to scroll height of radgrid in ascx. Pls help me with code.

When I get the scroll height fitting my screen, I shouldn't get the IE scrollbar? how do i do this

 I am facing one problem in RadGrid. After setting the FrozenColumnCount property, when I (horizontally) scrolled to the right end of the grid, it is leaving empty space (see the attach image). Here is the code which I am using.

<form id="form1" runat="server">
    <div>
    <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
   
    <telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="true" Width="100%">
        <MasterTableView HeaderStyle-Width="80px"></MasterTableView>
        <ClientSettings>
            <Scrolling AllowScroll="True" UseStaticHeaders="True" FrozenColumnsCount="2"></Scrolling>
            <Selecting AllowRowSelect="true" />   
        </ClientSettings>
    </telerik:RadGrid>
    </div>
    </form>

Code Behind is:

protected void Page_Load(object sender, EventArgs e)
    {
        RadGrid1.NeedDataSource += new GridNeedDataSourceEventHandler(RadGrid1_NeedDataSource);
        RadGrid1.PreRender += new EventHandler(RadGrid1_PreRender);
        RadGrid1.ItemDataBound += new GridItemEventHandler(RadGrid1_ItemDataBound);
    }

    protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        //RadGrid1.MasterTableView.AutoGeneratedColumns[7].HeaderStyle.Width = Unit.Pixel(40);
        //RadGrid1.MasterTableView.AutoGeneratedColumns[10].HeaderStyle.Width = Unit.Pixel(40);
    }

    protected void RadGrid1_PreRender(object sender, EventArgs e)
    {

    }

    protected void RadGrid1_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
    {
        RadGrid1.DataSource = GetResultsTable();
    }

    public DataTable GetResultsTable()
    {
        DataTable dt = new DataTable();

        for (int i = 0; i < 70; i++)
        {
            dt.Columns.Add("Column " + i);
            List<object> objectNumbers = new List<object>();

            for (int j = 0; j < 10; j++)
            {
                objectNumbers.Add(i.ToString() + "," + j.ToString());
            }

            while (dt.Rows.Count < objectNumbers.Count)
            {
                dt.Rows.Add();
            }

            for (int k = 0; k < 10; k++)
            {
                dt.Rows[k][i] = objectNumbers[k];
            }
        }
        return dt;
    }

I will really appreciate for quick response. Thanks
