How to dynamically bind asp.net repeater control to datasource

Question

I have a page with a simple dropdown and repeater control in page.on submit repeater control is bound to datasource1 which has 3 columns.

Answer 1

Try settings AutoPostback=true on your dropdownlist. Then, have a "selectedindexchanged" event handler on your codebehind setup to read the value and set the datasource accordingly, something similar to:

repeater1.DataSource=<yourdatasource>
repeater1.DataBind()

If your datasource is always using the same columns for your presentation, then this shouldn't be an issue. If your datasources will vary in the columns of data that they return, then Kashif's comment in your question may help you some. Otherwise, you just need to fill in the logic above to set the Datasource property of your repeater to whatever your datasource is...

Hope this helps

With bootstrap and datatables.net plugins

protected void rptReport_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.Header)
            {
                Repeater headerRepeater = e.Item.FindControl("Header1") as Repeater;
                headerRepeater.DataSource = dtOrder.Columns;
                headerRepeater.DataBind();
            }

            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                Repeater columnRepeater = e.Item.FindControl("Item1") as Repeater;
                var row = e.Item.DataItem as System.Data.DataRowView;
                columnRepeater.DataSource = row.Row.ItemArray;
                columnRepeater.DataBind();
            }
        }

Feels below code will help you .

<asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
    <HeaderTemplate>
        <tr class="">
            <asp:Repeater ID="Header1" runat="server">
                <ItemTemplate>
                    <th align="left"><%# Container.DataItem %>
                    </th>
                </ItemTemplate>
            </asp:Repeater>
        </tr>
    </HeaderTemplate>
    <ItemTemplate>
        <tr class="">
            <asp:Repeater ID="Item1" runat="server">
                <ItemTemplate>
                    <td><%# Container.DataItem %>
                    </td>
                </ItemTemplate>
            </asp:Repeater>
        </tr>
    </ItemTemplate>
</asp:Repeater>


protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e) 
    {
        if (e.Item.ItemType == ListItemType.Header)
        {
            Repeater headerRepeater = e.Item.FindControl("Header1") as Repeater;
            headerRepeater.DataSource = dt.Columns;
            headerRepeater.DataBind();
        }

       if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            Repeater columnRepeater = e.Item.FindControl("Item1") as Repeater;
            var row = e.Item.DataItem as System.Data.DataRowView;
            columnRepeater.DataSource = row.Row.ItemArray;
            columnRepeater.DataBind();
        }
    }

or in other way using 2 different User control.First user control contain repeater1, second contain repeater2.Then dynamic add these repeaters to your page, at code behind

Answer 5

You can simply use like this -

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
   using (SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["RBConnectionString"].ConnectionString))
   {
      SqlCommand cmd = new SqlCommand("select * from Customers", con);
      cmd.CommandType = CommandType.StoredProcedure;
      SqlDataAdapter adpt = new SqlDataAdapter(cmd);
      DataTable dt = new DataTable();
      adpt.Fill(dt);
      repeaterObj.DataSource = dt;
      repeaterObj.DataBind();
      cmd.Dispose();
    }
 }
