I have a radGrid that has several rows.  One of the rows is a row that cannot be deleted by the user.  I would like to hide the row from view.  What event would I use to hide the row and what is the code to hide the row.

Hello Richard,

In order to achieve this try the following code snippet in ItemDataBound event.

C#:

Thanks,
Princy.

Princy,

Hi there. How do you hide the rows by setting conditions to a non-data key value columns? For example if I set condition to data key value "CustomerID", it works but If I set data key value to "CompanyName", I can't hide the row.  I would like to hide the row based on the value of "CompanyName" instead of "CustomerId". 

 
This works:

 

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

 

{

 

 

    if (e.Item is GridDataItem && e.Item.OwnerTableView.Name == "Master")

 

        {

 

            GridDataItem item = (GridDataItem)e.Item;

 

 

            if (item.GetDataKeyValue("CustomerID").ToString().Substring(0, 1) == "A")

 

 

            {

            item.Display =

false; //hide the row

 

            }

        }

    }

This does not work..

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

 

{

 

 

    if (e.Item is GridDataItem && e.Item.OwnerTableView.Name == "Master")

 

        {

 

            GridDataItem item = (GridDataItem)e.Item;

 

 

            if (item.GetDataKeyValue("CompanyName").ToString().Substring(0, 1) == "A")

 

 

            {

            item.Display =

false; //hide the row

 

 

 

 

 

            }

        }

    }

 

Thanks

Please disregard my earlier thread. It is solved. Correct syntex should be below  because CompanyName is not a GetDataKeyValue.

Thanks Princy and others.

Hello,

One option is you can access the cell value by using ColumnUniqueName'. Please refer the following documentation
Accessing cells and rows

Another option to get the data for the column 'CompanyName' is by adding the field name to the DataKeyNames property.

Hello guys,

I am doing my program in silverlight 5. Unfortunately, i cant seem to find the namespace GridItemEventArgs, or ItemDataBound event, or event the GridDataItem.
I'm currently using Telerik.Windows.Controls.GridView.RowLoadedEventArgs e, however, when i used 

e.Row.Visibility = System.Windows.Visibility.Collapsed;

the row is not visible but it leaves a row of blank space.How can i hide it without leaving the white blank space?
Thanks..

Hello Anna,

The mentioned namespace and events are available only for the RadGrid control for ASP .NET Ajax. Note that in case you have any issues with the RadGridView control for Winforms you should post you question in the Winforms forums.

Hi Princy,

I've tried everything but cannot get my row to hide. The database table is named Archived and I want to be able to hide it from view if it is Archived. Please see code below. Thank you.

 

 

public partial class ProjectGridView : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{

if (!IsPostBack)
bindParentData();

}

private void bindParentData()

rgResults.DataSource = Status.GetStatesByType(StatusType.Project);
rgResults.DataBind();
}

        //public void BindData(int id)
        //{

        //}
