I have a button that uploads the selected file through RadInput. However, if the user clicks it and the selected file input is blank it errors. How can I check whether the RadInput is blank or null so I can send a custom error. Or can I hook it up to a validator?

Grid pivot table question

In my datasource, there are some columns that I get back that I don't wish to display. I know you can change the column attributes to hide a column, but in this case with a pivot table the column would now be a row that would have to hide. How do I go about doing something like that, is it even possible?

How do I get a CheckBox in a RadGrid

I have several checkboxes in a RadGrid and checkBoxe 4 does an AutoPostback to DoSomething(object obj, EventArgs e).

This works great and I don't want change anything and I use datakeys to get my values from the row. I also don't want to loop through GridDataItems to find out if checkbox 1-3 are checked.

<telerik:GridTemplateColumn HeaderText="Comments" ItemStyle-HorizontalAlign="Left" HeaderStyle-Width="250px" Groupable="false" ItemStyle-VerticalAlign="Top" UniqueName="CheckBoxes">

<ItemTemplate>

<asp:CheckBox ID="CheckBox1" Text="CheckBox 1" runat="server" /><br />

<asp:CheckBox ID="CheckBox2" Text="CheckBox 2" runat="server" /><br />

<asp:CheckBox ID="CheckBox3" Text="ChcekBox 3" runat="server" /><br />

<asp:CheckBox ID="CheckBox4" Text="CheckBox 4" OnCheckedChanged="DoSomething" AutoPostBack="True" runat="server" />

</ItemTemplate>

</telerik:GridTemplateColumn>

II would like to see of the checkboxes for 1-3 are checked, since checkbox 4 is firing the postback "DoSomething".

protected void DoSomething(object obj, EventArgs e)

{

CheckBox checkBox1 = (CheckBox)obj;

GridDataItem checkedOffer = (obj as CheckBox).NamingContainer as GridDataItem;

if ((obj as CheckBox).Checked)

{

// I need to find the other checkboxes in here when someone clicks on CheckBox 4

}

Thank you in advance!
