Hello Carlos,

Check out the following code to eliminate the RefreshButton.
CS:

if (e.Item is GridCommandItem)

{

GridCommandItem cmditm = (GridCommandItem)e.Item;

//To eliminate the image button

Button btn1 = (Button)cmditm.FindControl("RefreshButton");

btn1.Visible = false;

//To eliminate the LinkButton

LinkButton lnkbtn1 = (LinkButton)cmditm.FindControl("RebindGridButton");

lnkbtn1.Visible = false;

}

Also, check out the code below for hiding a column in the DetailTable.
ASPX:

<DetailTables>
        <telerik:GridTableView Name="Detail1"  DataSourceID="SqlDataSource3">
              <Columns>
                   <telerik:GridBoundColumn DataField="FirstName" HeaderText="FirstName" UniqueName="FirstName" ></telerik:GridBoundColumn>
                   <telerik:GridBoundColumn   DataField="ToandFro" HeaderText="ToandFro" UniqueName="ToandFro"  ></telerik:GridBoundColumn>
              </Columns>
        </telerik:GridTableView>
</DetailTables>

CS:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
       if ((e.Item is GridDataItem) && (e.Item.OwnerTableView.Name == "Detail1"))
        {
            foreach(GridColumn column1 in e.Item.OwnerTableView.RenderColumns)
            {
                if (column1.UniqueName == "FirstName")
                {
                    column1.Visible = false;
                }
            }
        }
    }

Thanks
Princy.

Hello Princy.

Thanks for your reply, there is no doubt that solves all my problems, but is there a way to do the same inside Page_Load like:

if (permisos[0].mod_cat == "1"){
  RadGrid1.Columns.FindByUniqueName("EditColumn1").Visible = false;
  RadGrid1.Columns.FindByUniqueName("DeleteColumn1").Visible = false;
}

where Editcolumn1 and DeleteColumn1 are UniqueName for columns in MasterTable and the columns i want to hide are inside DetailTable.

Regarding your sugestion abour refresh button i just dont get what are you refering with e.item, i would also like to do it from Page_Load.


Thanks for your help.

Hi Carlos,

You can hide columns on PageLoad event as shown below.

CS:

 protected void Page_Load(object sender, EventArgs e)
    {
       // To hide a column in the MasterTableView
        RadGrid1.MasterTableView.GetColumn("FirstName").Visible = false;
       // To hide a column in the DetailTable
        RadGrid1.MasterTableView.DetailTables[0].GetColumn("FirstName").Visible = false;
     }

And you could eliminate the RefreshButton in the ItemDataBound event as shown below.

CS:

 protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
      if (e.Item is GridCommandItem)
        {
            GridCommandItem cmditm = (GridCommandItem)e.Item;
            Button btn1 = (Button)cmditm.FindControl("RefreshButton");
            btn1.Visible = false;
            LinkButton lnkbtn1 = (LinkButton)cmditm.FindControl("RebindGridButton");
            lnkbtn1.Visible = false;
       }
    }

Thanks
Princy.

Hi princy.

i'm sorry i was moved from this project to another one with higher priority, i just came back to this one, i checked code you sent me and now it work fine, i just added OnItemDataBound="RadGrid1_ItemDataBound" to my radgrid properties.

thanks.

The above code doesn't work (both columns are hidden).

How do I hide a column and its header per row based on the row's data?

Hi,

Try the following code to achieve your scenario.
C#:

protected void RadGrid2_ItemDataBound(object sender, GridItemEventArgs e)
{
  if (e.Item is GridDataItem && e.Item.OwnerTableView.Name == "DetalTable1")
  {
     GridTableView detailTable = (GridTableView)e.Item.OwnerTableView;
     detailTable.GetColumn("Uniquename").Display = false;
  }
}

Thanks,
Shinu.
