获取Telerik RadGrid的行

Question

I'm working on a RadGrid, and I want to access its rows but it seems it does not have a .Rows property.

Here's what I have tried until now:

How can I access rgCustomers 's Rows collection? I want to add a button to each row.

Answer 1

According to Telerik's documentation ,

"Each dynamic row in the grid represents a record from the specified data source. Dynamic rows are represented by the GridDataItem class (a descendent of GridItem).

Each GridTableView has a set of rows (the Items collection) of type GridDataItem."

So you want to use the Items collection of the grid, which is a collection of GridDataItems.

protected void btnLoad_Click(object sender, EventArgs e)
{
  rgCustomers.DataSource = odsCustomers;
  rgCustomers.DataBind();
  foreach (GridDataItem row in rgCustomers.Items)
  {
  }
}

Answer 2

I'm assuming it's WPF/Silverlight RadGrid?

If You want to access row control in databound grid (not row data) - You'll have to use ItemContainerGenerator property of RadGrid. For example:

rgCustomers.ItemContainerGenerator.ContainerFromIndex(0);

or

rgCustomers.ItemContainerGenerator.ContainerFromItem(odsCustomers[0]);

will return first row control (of type RadGridViewRow if I remember correctly)

Answer 3

- If you want to add a button on every row:

GridTemplateColumn or GridButtonColumn will do the trick.

- If you want to access the current row:

1. Use the OnClick event handler of the button.

    <telerik:RadButton ID="BTN_DEMO" runat="server" HeaderText="N°1 DEMO BTN" Text='<%#"Click Me iM N°"+((IhateEvalDataSource) Container.DataItem).Stuff_ID %>' OnClick="BTN_DEMO_Click"></telerik:RadButton> 

2. Get a reference to the GridDataItem using (sender as RadButton).NamingContainer.

    protected void BTN_BL_Click(object sender, EventArgs e) { GridDataItem G = ((RadButton)sender).NamingContainer as GridDataItem; } 

3. Use GetDataKeyValue() method to extract the record ID:

    DEMO_INT = (int)G.GetDataKeyValue("mySweetInt"); DEMO_STRING = (string)G.GetDataKeyValue("MyString");
