Then.. RoleID might be primary key or identity which is not allowed to add NULL value.
if you wanna add it then you may change your database design.
if I'm in wrong direction then you can show me your current table design.

Check it out here.. >> [RoleId] [uniqueidentifier] NOT NULL,
that means this column doesn't accept any NULL value.
Why do you want to add NULL value?
it will work if you don;t add any NULL value to this column..
However, in case you have to add NULL value then... you can remove "NOT NULL" from this statement..

Your welcome. my friend.

we cannot take button in gridview in this way. IT gives error .
Error 1 System.Web.UI.WebControls.DataControlFieldCollection must have items of type 'System.Web.UI.WebControls.DataControlField'.'asp:Button' is of type 'System.Web.UI.WebControls.Button'.
|
|
|
|
|
Try the code which I gave as I am doing this only and its working in my Project. The only difference is that I am using image button and u r using button.

Hi ritu
u can take server bottun between <ItemTemplate> tag.
i give u whole code how to take a button
now try this code
<asp:GridView ID="GV_cart" runat="server" AutoGenerateColumns="False"
OnRowCommand="GV_cart_RowCommand" CellPadding="4" ForeColor="#333333">
<Columns>
<asp:BoundField DataField="fileid" HeaderText="File Id" />
<asp:BoundField DataField="Filename" HeaderText="File Name" />
<asp:TemplateField>
<HeaderTemplate>File id</HeaderTemplate>
<ItemTemplate>
<asp:Button ID="BT" runat="server" CommandName="button" CommandArgument='<%#Eval("fileid") %>' Text="Button" Width="75px" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
After this write code on Row_command event
if (e.CommandName == "button")
{
string fileid= e.CommandArgument.ToString();
}
if u use more than one button than this code may be useful for checking which button evet fires by commandname condition.
