Я хочу связать DropDownlist, который находится внутри ретранслятора. Мой код
<asp:Repeater ID="rep_UnAssignComps" runat="server">
<ItemTemplate><asp:DropDownList ID="drp_CompPropAddress" runat="server">
</asp:DropDownList></itemTemplate></asp:Repeater>
используйте это
<asp:Repeater ID="rptCustomers" runat="server" OnItemDataBound="OnItemDataBound">
<HeaderTemplate>
<table cellspacing="0" rules="all" border="1">
<tr>
<th scope="col" style="width: 80px">
Customer Id
</th>
<th scope="col" style="width: 120px">
Name
</th>
<th scope="col" style="width: 100px">
Country
</th>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td>
<asp:Label ID="lblCustomerId" runat="server" Text='<%# Eval("CustomerId")
%>' />
</td>
<td>
<asp:Label ID="lblName" runat="server" Text='<%# Eval("ContactName") %>'
/>
</td>
<td>
<asp:DropDownList ID="ddlCountries" runat="server">
</asp:DropDownList>
</td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
и в codebehind:
protected void OnItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType ==
ListItemType.AlternatingItem)
{
//Find the DropDownList in the Repeater Item.
DropDownList ddlCountries = (e.Item.FindControl("ddlCountries") as DropDownList);
ddlCountries.DataSource = this.GetData("SELECT DISTINCT Country FROM Customers");
ddlCountries.DataTextField = "Country";
ddlCountries.DataValueField = "Country";
ddlCountries.DataBind();
//Add Default Item in the DropDownList.
ddlCountries.Items.Insert(0, new ListItem("Please select"));
//Select the Country of Customer in DropDownList.
string country = (e.Item.DataItem as DataRowView)["Country"].ToString();
ddlCountries.Items.FindByValue(country).Selected = true;
}
}
