[Solved] RadGrid GridButtonColumn Link Header Text

[Mahesh Babu Immedisetty]

Hi,

I have a radGrid to which I am adding GridButtonColumn of type link at runtime. When I click on that link, it is calling  my code behind item command. I am able to retrive text and index from GridCommandEventArgs. I want to know how to get the header text that this link is clicked.

Please provide me some solution.

    protected void radGrid_ItemCommand(object source, GridCommandEventArgs e)
    {
        if (e.CommandSource.ToString() == "Telerik.Web.UI.GridLinkButton")
        {
            LinkButton lb = (LinkButton)e.CommandSource;
            string text = lb.Text;
            int index = e.Item.DataSetIndex;
        }
    }


Thanks,
Mahesh

Hi Mahesh,

I hope you are trying to access the HeaderText of the Button column on clicking the LinkButton. If so try the following approach and see whether it helps.

CS:

  protected void RadGrid2_ItemCommand(object source, GridCommandEventArgs e)
    {

        if (e.CommandName == "MyCommand")
        {
            GridItem[] header = RadGrid2.MasterTableView.GetItems(GridItemType.Header);
            GridHeaderItem headerItem = (GridHeaderItem)header[0];
            string strTxt = ((LinkButton)headerItem["BtnCol"].Controls[0]).Text;
        }

    }

Thanks for the response Princy.

I am having some issue with the code that you supplied. Looks like I am missing something here. I am getting the following exception while trying to get the header text.

Cannot find a cell bound to column name 'Name'

I am adding column to radGrid -> MasterTableView as this:

  GridButtonColumn gc1 = new GridButtonColumn();

        gc1.DataTextField = "Name";

        gc1.HeaderText = "Name";

        gc1.CommandName = "Name";

        gc1.ButtonType = GridButtonColumnType.LinkButton;

I am trying to access the value like this:

protected void radGrid_ItemCommand(object source, GridCommandEventArgs e)

    {

        if (e.CommandName == "Name")

        {

            GridItem[] header = radGrid.MasterTableView.GetItems(GridItemType.Header);

            GridHeaderItem headerItem = (GridHeaderItem)header[0];

            string strTxt = ((LinkButton)headerItem["Name"].Controls[0]).Text;

        } 

    }

Am I missing something here??

Please help.

Thanks,

Mahesh

I got it. I forgot to set UniqueName property.

Thanks a lot Princy for your help.

I am facing issue when I am adding GridColumns in Page_Load. I am getting e.CommandName as empty in radGrid_ItemCommand method.

If I create columns in Page_Init() everything is going fine.

I want to add columns only when my page is loaded successfully.

Please help.

I think I want to be clear on my requirement.

I have a radGrid in which there are two link columns( Lets take RollNO and Name). User can click on any link. Now, I want to know which GridButtonColumn he clicked.

The way that you have suggested can give me header text only when I know the button column name. This way I can get the header text but I dont whether the user clicked RollNo or Name.

Please suggest some workaround.

Hi Mahesh,

Give a try with the following approach and see whether it is helpful.

CS:

 protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
     {
         if (e.Item is GridDataItem)
         {
             GridDataItem item = (GridDataItem)e.Item;
             LinkButton linkBtn1 = (LinkButton)item["RollNO"].Controls[0];
             linkBtn1.CommandArgument = "RollNO";

             LinkButton linkBtn2 = (LinkButton)item["Name"].Controls[0];
             linkBtn2.CommandArgument = "Name";
         }

    }

 protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
    {

        if (e.CommandSource.ToString() == "Telerik.Web.UI.GridLinkButton")
        {
            string columnName = e.CommandArgument.ToString();
        }

    }

Thanks
