Re: Validator.RenderControl(htmlTextWriter) returns empty string?

Hello and thanks for your reply! Actually this did solve part of the problem. Now I do get html for the validators like this:

span id="Login1_validatorReqFieldUserName" style="color: Red; display: none;"

but I don´t seem to get the javascripts that makes the actual validation work.

your error is a big clue, which line of the code does it have a problem with, is it this line:

TextBox1.Text = cClass.dataReader.Item("Type").ToString

It depends how your website functions.
Have you previously copied a dll across?
I know that if you write the c# in visual studio and then upload dll then the most updated pages of code must be in that dll
To answer your question then yes put it in the dll

How to select your row?

in your ASP you can do

<ItemTemplate>
                                    <asp:ImageButton runat="server" ID="imgAnnul" CssClass="GridPlaatje" ImageUrl="~/Images/NewDesign/trashcan.png" CommandName="AnnulGrid" AlternateText="Delete" OnCommand="Grid_OnCommand" /><asp:ImageButton runat="server" ID="imgEdit" CssClass="GridPlaatje" ImageUrl="~/Images/NewDesign/pencil.png" CommandName="EditGrid" AlternateText="Edit" OnCommand="Grid_OnCommand" />
                                </ItemTemplate>

in your code behind you create the method

protected void Grid_OnCommand(Object sender, CommandEventArgs e)

which has the next lines of code

ImageButton btn = (ImageButton)sender;
        GridViewRow row = (GridViewRow)btn.NamingContainer;  // this gives you the selected DataRow from the GridView
        if (e.CommandName.Equals("EditGrid"))
        {
            radgrid1.EditIndex = row.RowIndex;
        }
        else if (e.CommandName.Equals("CancelItem"))
        {
            radgrid1.EditIndex = -1;
        }
        else if (e.CommandName.Equals(<name you="" choose="">))
        { 
             // your code
        }
        radgrid1.SelectedIndex = -1;
</name>

Hi,

I am using the MVVM Pattern to develop a wpf application.
Here I am unable to bind the selected row of a datagrid from view to viewmodel.
the code is like this:

<telerik:RadGridView ReorderColumnsMode="Interactive" Height="251" HorizontalAlignment="Left" SelectedItem="{Binding SelectedListCollection,Mode=Default}" Width="Auto" AutoGenerateColumns="False" ItemsSource="{Binding UserListCollection, Mode=TwoWay}">

both the SelectedListCollection and UserListCollection are of same type.

ObservableCollection<UserEntity>SelectedListCollection
ObservableCollection<UserEntity>UserListCollection

Can any one help me please....

Thanks in advance.

So i used this code after databind in my grid...,

{
gvViewData.Columns[0].ItemStyle.Width = Unit.Percentage(10);
gvViewData.Columns[1].ItemStyle.Width = Unit.Percentage(20);
gvViewData.Columns[2].ItemStyle.Width = Unit.Percentage(40);
gvViewData.Columns[3].ItemStyle.Width = Unit.Percentage(15);
gvViewData.Columns[4].ItemStyle.Width = Unit.Percentage(15);
}

But its not at all considering the what i have allocated for my items...,
