[Solved] RadGrid links to GridBoundColumns at runtime

[Mahesh Babu]

Hi,

I have a radgrid which is bound to a datatable. I want to assign navigation urls to values of columns in that radgrid. Is there anyway to perform this logic at runtime.

I am able to do this at design time like this:

 <telerik:GridTemplateColumn HeaderText="Account Name" UniqueName="Account" SortExpression="Account" ItemStyle-Width="100px" >
                                        <ItemTemplate>
                                        <a href="accountview.aspx?id=<%# Eval("AccountID") %>"><%# Eval("AccountName")%></a>
                                        </ItemTemplate>
                                        <ItemStyle Width="100px" Font-Underline="true"></ItemStyle>
                                    </telerik:GridTemplateColumn>


But my issue is, i am generating these columns at runtime. so, I need to assign urls at runtime only. Please let me know any way to do this at runtime.

Thanks,
Mahesh

Hi Mahesh,

Try the following code snippet in order to add the links from code behind.

ASPX:

  . . .
<MasterTableView DataSourceID="SqlDataSource1" DataKeyNames="AccountID, AccountName">
  . . .

C#:

protected void Page_Load(object sender, EventArgs e)
{
    GridTemplateColumn tempCol = new GridTemplateColumn();
    RadGrid1.MasterTableView.Columns.Add(tempCol);
    tempCol.UniqueName = "AccountLink";
    tempCol.HeaderText = "Account";
}
protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem item = (GridDataItem)e.Item;
        HyperLink hl = new HyperLink();
        hl.NavigateUrl = "Default.aspx?id=" + item.GetDataKeyValue("AccountID").ToString();
        hl.Text = item.GetDataKeyValue("AccountName").ToString();
        item["CustomerIDLink"].Controls.Add(hl);
    }
}

Is there any way to add this to a GridBoundColumn at runtime???

Hi Mahesh,

I tried following code in order to achieve this by using GridBoundColumn instead of GridTemplateColumn. Give a try with following code snippet.

ASPX:

  . . .
<MasterTableView DataSourceID="SqlDataSource1" DataKeyNames="AccountID, AccountName">
  . . .

C#:

protected void Page_Load(object sender, EventArgs e)
{
    GridBoundColumn boundcolumn = new GridBoundColumn();
    RadGrid1.MasterTableView.Columns.Add(boundcolumn);
    boundcolumn.UniqueName = "AccountIDHyperLink";
    boundcolumn.HeaderText = "AccountIDHyperLink";
}

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem item = (GridDataItem)e.Item;
        HyperLink hl = new HyperLink();
        hl.NavigateUrl = "Default.aspx?id=" + item.GetDataKeyValue("AccountID").ToString();
        hl.Text = item.GetDataKeyValue("AccountName").ToString();
        item["AccountIDHyperLink"].Controls.Add(hl);
    }
}
