Hi Telerik team,

I have placed multiple user controls inside a Dock zone. Controls loaded fine. Each user control contains multiple controls. I want to access the control values for saving reports.

Example: Rad Dock contains two user controls A, B.
A has two combo boxes and a textbox
B has two radio buttons and a text box.
I need to access the control values inside the user control from the Rad dock .

Please let me know, whether its possible or not.

Thanks,
Nag

hi all,
   I am using editform to edit my data in radgridview. EditFormType is 'Autogenerated'. I have one problem in insert mode.
I have one status column in the grid. This is not a visible column and i need to show this column in edit mode only. In normal mode and insert mode i need not siplay this control. I specify the template column in grid view as follows


In my databound event i try to set visibility of this column. checkbox will hide in the insert mode but the header text exists the same. how to handle that header text also. my code behind is

Only checkbox is hide. please help to handle that header text. If i didnt put header text in design mode, ':' is visible. how to handle this colon (:) in the editmode

My grid is databound to List<Entity>

Edit mode is:

EditForm is template:

I want to customize pop-up caption that it will say 'You are editing item {number}'.

I cannot use CaptionFormatString because {number} is not my Entity property. It is just subsequent number and it can be DataItem.ItemIndex as well.

I may set it declaratively or in code-behind but how to extract DataItem.ItemIndex of editing row?

This is my ascx code

My problem is that I don't know how to bind a DDL in code behind in order to Insert or Edit

I have this codebehind:

protected void gv_data_Contract_ItemDataBound(object sender, GridItemEventArgs e)
    {

        if (e.Item is GridEditableItem && e.Item.IsInEditMode)
        {
            GridEditableItem item = e.Item as GridEditableItem;
            // access/modify the edit item template settings here
            DropDownList list = item.FindControl("lbl_gv_data_PersonCompanyName") as DropDownList;
            list.DataSource = GetCompany();
            list.DataBind();

            if (Session["Updated"] != null)
            {
                list.SelectedValue = Session["updatedValue"].ToString();
            }
        }
        else if (e.Item is GridDataItem && !e.Item.IsInEditMode && Page.IsPostBack)
        {
            GridDataItem item = e.Item as GridDataItem;
            Label label = item.FindControl("ddl_gv_person") as Label;
            // update the label value
            if (label != null) label.Text = Session["updatedValue"];
        }

    }

And I get this error

System.NullReferenceException was unhandled by user code
  Message="Object reference not set to an instance of an object."
 

A script that mistake can be solved?
