I have a RadGrid with a DetailTable in it. When I expand a row in the MasterView to show the Detail, I want to change the detail row's Edit link text based on the data in the detail row.

For example if the row has col1="Blah", then I want the edit text to be "Edit Blah" instead of "Edit".

What's the easiest way to do this?

DraggedNodes object is null

Hi,
I have a TreeView and RadGrid width drag and drop functionality (drag from TreeView and drop to RadGird). To Detect which node is dropped on RadGrid, I have added a nodeDrop handler to TreeView. So When i drop a node on RadGrid, nodeDrop handler fires, but SourceDragNode and DraggedNodes of RadTreeNodeDragDropEventArgs parameter are null. This happens just when I move TreeView and RadGrid to an UserControl.
What things may cause this issue?

I have checked my post data at client side, an it seems OK (dropped node index has correct value ).

any idea is appreciated.

RadFormDecorator focus not working on IE7

Hi,

Using the RadFormDecorator (Q1 2008.1.619.20), setting the focus on any control on IE7 does not work but works as expected in Firefox. Remove RadFormDecorator and IE7 works correctly.

    
            <body> 
        
                <form id="form1" runat="server"> 
        
                <telerik:RadFormDecorator ID="RadFormDecorator1" runat="server" DecoratedControls="Buttons" 
        
                    Skin="Sunset" /> 
        
                <AjaxToolKit:ToolkitScriptManager EnablePartialRendering="true" ID="ScriptManager1" 
        
                    runat="server" CombineScripts="true" /> 
        
                <div> 
        
                    <br /> 
        
                    <telerik:RadComboBox ID="RadComboBox1" runat="server" MarkFirstMatch="true"> 
        
                        <Items> 
        
                            <telerik:RadComboBoxItem Value="" Text="" /> 
        
                            <telerik:RadComboBoxItem Value="1" Text="1" /> 
        
                            <telerik:RadComboBoxItem Value="2" Text="2" /> 
        
                        </Items> 
        
                    </telerik:RadComboBox> 
        
                    <br /> 
        
                    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> 
        
                    <asp:Button ID="button1" runat="server" Text="submit" CssClass="testx" /> 
        
                </div> 
        
                </form> 
        
            </body>

    
            Protected Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender 
        
                    ScriptManager.GetCurrent(Page).SetFocus(RadComboBox1) 
        
                End Sub

Is there any work around for this?
Thanks,
Khanh

Keeping the image format on thumbnail

All thumbnails are saved in .png format. How can I keep the original image's format on thumbnails? If I edit on a .jpg image, I want the thumbnail also to be a .jpg image.
This is what I have tried with no success:

protected void RadImageEditor1_ImageSaving(object sender, ImageEditorSavingEventArgs args)

{

var thumbImage = args.Image.Clone();

var pathToThumbs = "~/Filarkiv/thumb/";

thumbImage.Resize(96, 96);

var ms = new MemoryStream();

thumbImage.Image.Save(ms, args.Image.RawFormat);

File.WriteAllBytes(String.Format("{0}{1}.{2}", MapPath(pathToThumbs), args.FileName, args.Image.Format), byte[])ms.ToArray());

}

Q3 2012 adds border

Since upgrading to q3 2012 from q2, an extraneous extra border is added around the control. Not the border that is set by the control's property settings but another around the control... is this a bug?

Here is a sample code page and screenshot (IE9 on Win7) (attached)

I have deliberately made the actual control border red solid to show the issue.

Extra columns during PDF export

PDF export of X columns is producing another extra X blank columns. This must be some really simple error, but I just can't find it. Here's the code:

<asp:Button ID="ExportToPDF" runat="server" Text="ExportToPDF"

OnClick="ExportToPDF_Click"/>

<telerik:RadGrid ID="RadGrid2" runat="server" GridLines="Vertical" AutoGenerateColumns="false" Width="800px">

<ExportSettings ExportOnlyData="true"></ExportSettings>

</telerik:RadGrid>

public partial class gridtest : System.Web.UI.UserControl

{

int iNumCols = 5;

protected void Page_Init(object sender, EventArgs e)

{

CreateRadGrid2();

}

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

FillRadGrid2();

}

internal void CreateRadGrid2()

{

for (int iCol = 0; iCol < iNumCols; iCol++)

{

GridBoundColumn col = new GridBoundColumn();

col.HeaderText = "Col"+iCol.ToString();

col.DataField = "Col"+iCol.ToString();

RadGrid2.MasterTableView.Columns.Add(col);

}

internal void FillRadGrid2()

{

// create an empty data table, matching the bound columns of the grid

DataTable dt = new DataTable();

for (int iCol = 0; iCol < iNumCols; iCol++)

dt.Columns.Add("Col"+iCol.ToString());

// fill in the data for the rows

for (int iRow = 0; iRow < 5; iRow++)

{

DataRow dr = dt.NewRow();

for (int iCol = 0; iCol < iNumCols; iCol++)

dr["Col" + iCol.ToString()] = "R" + iRow.ToString() + "C" + iCol.ToString();

dt.Rows.Add(dr);

}

RadGrid2.DataSource = dt;

RadGrid2.DataBind();

}

protected void ExportToPDF_Click(object sender, EventArgs e)

{

this.RadGrid2.MasterTableView.ExportToPdf();

}

The resulting PDF is attached.

Please can you advise how to resolve this

Grid ViewState Not Preserving

Hi, all.

I have a question regarding the RadGrid's view state on the client side. I have a RadGrid sitting inside an .ascx control that is embedded inside a RadDock. I have the grid's EnableViewState property set to "true" and the GroupingEnabled property set to "true", the MasterTableView's GroupLoadMode set to "client" and the CientSettings have the AllowDragToGroup property set to "true". The grid is wrapped in an UpdatePanel, and it's also tied to a RadAjaxManagerProxy control since I already have a RadAjaxManager on the master page.

The control loads just fine, and I can group one item. However, when I go to group another item, the first grouping level is removed; I can effectively have only one group set (the data itself is rebinding properly). If I try a sort while the group is in place, it's also removed after the sort finishes. In addition, if I try to remove the one group that's there, I get an Index Out of Range Javascript error.

From what I can tell, I have the grid set up properly. Is there something else I need to take into account to preserve the view state?
