Programmatic Retrieval of a Grid Items Value

[James Legan]

Since there is not RadListbox, I have started to use RadGrid in its place.

I have a need to programmatically access the value of a particular grid item. All of the client-settings are enabled to allow for a selectedindexchanged event. There is a series of 5 grids that are programmatically built based on the selection in the previous grid.

The first grid is bound to a simple List<string>.

 

// Grid Code

 

rgDailyBuilds.DataSource = oDailyBuildFolder.DailyBuilds.ToList<

string>();

 

rgDailyBuilds.DataBind();

On the selected index change, I need to access the value of the grid item that was selected. Currently, I only allow for single select but in the future I will allow multiple select. That said, I started to approach it like this:

 

// Grid Code

 

 

 

GridItemCollection oGic = rgDailyBuilds.SelectedItems;

 

 

string sValue = string.Empty;

 

 

foreach (GridDataItem o in oGic)

 

    sValue =

Convert.ToString(o.GetDataKeyValue("Item"));

But didn't get far. How can I access the values? Also, what if the grid contained more than one column. How would I retrieve the value from a single column of a row?

Thanks,

Jim

Hello James,

I already answered your support ticket. Sample code-snippet is shown below:

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">
    <asp:Button ID="Button1" runat="server" Text="Get selected items"
        onclick="Button1_Click" />
    <telerik:RadGrid ID="RadGrid1" runat="server" Skin="Vista" ShowHeader="false" AllowMultiRowSelection="true"
        Width="200px">
        <ClientSettings Selecting-AllowRowSelect="true" EnablePostBackOnRowClick="true" />
    </telerik:RadGrid>
</telerik:RadAjaxPanel>

protected void Button1_Click(object sender, EventArgs e)
{
    string message = "";
    foreach (GridDataItem item in RadGrid1.SelectedItems)
        message += item["ID"].Text + "\n";
    RadAjaxPanel1.Alert(message);
}

protected void Page_Load(object sender, EventArgs e)
{
    DataTable table = new DataTable();
    table.Columns.Add("ID", typeof(int));
    for (int row = 0; row < 10; row++)
        table.Rows.Add(row);

    RadGrid1.DataSource = table;
}
