And my question:
I cant bound datavaluefield and datatextfiled. If I write as defined above. I got this errror.
DataBinding: '<>f__AnonymousType1`8[[System.Nullable`1[[System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]], mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Nullable`1[[System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]], mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Nullable`1[[System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]], mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Collections.Generic.IEnumerable`1[[<>f__AnonymousT...' does not contain a property with the name 'OptionName'.
How can I bind value and text.
Thanks.
The error explains itself clearly:
does not contain a property with the name 'OptionName'
Just change this (in both, your declaration of RadioButtonList
and CheckBoxList
):
DataTextField='<%#Eval("OptionName")%>' DataValueField='<%#Eval("OptionId")%>'
To:
DataTextField="OptionName" DataValueField="OptionId"
And that's it, you do not need to evaluate the binding, just specify the name of the property. The rest of your code looks good
As Requested, to get the selected item from the RadioButtonList
:
<asp:GridView runat="server" OnRowCommand="grdProducts_RowCommand" ID="grdProducts">
<Columns>
<asp:TemplateField ShowHeader="False">
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="false"
CommandName="myLink" CommandArgument='<%# DataBinder.Eval(Container, "RowIndex") %>' Text="Button"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:RadioButtonList DataTextField="NestedValue" DataValueField="ID" runat="server" DataSource='<%# Eval("Nested") %>' ID="radios">
</asp:RadioButtonList>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:Label runat="server" ID="lblMessage" />
Code behind:
protected void grdProducts_RowCommand(object sender, GridViewCommandEventArgs e)
{
switch (e.CommandName)
{
case "myLink":
var row = this.grdProducts.Rows[int.Parse(e.CommandArgument.ToString())];
var radios = row.FindControl("radios") as RadioButtonList;
this.lblMessage.Text += "<br/>" + radios.UniqueID;
this.lblMessage.Text += "<br/> dedede " + radios.SelectedValue;
break;
}
}
