Error while deletion of data in gridview.

Question

The Declarative Approach While using TemplateField, we can directly use the OnClientClick event of the LinkButton Server control and call JavaScript confirm function, as given below. "lnkDelete" runat= "server" OnClick= "lnkDelete _Click" OnClientClick= "return confirmOnDelete('');" >Delete The Code behind Approach The Code Behind approach is almost the same, as we did using the RowDataBound event to access the ShowDeleteButton. The output is given below. protected void gvEmployee_RowDataBound( object sender, GridViewRowEventArgs e) { if (e.Row.RowState != DataControlRowState.Edit) // check for RowState { if (e.Row.RowType == DataControlRowType.DataRow) //check for RowType { string id = gvEmployee.DataKeys[e.Row.RowIndex].Value.ToString(); //cast the ShowDeleteButton link to linkbutton LinkButton lb = (LinkButton)e.Row.Cells[4].FindControl( "lnkDelete" ); if (lb != null ) { //attach the JavaScript function and pass the ID as the paramter lb.Attributes.Add( "Onclick" , "return confirmOnDelete('" + id + "');" ); } } } } It shows as error

hi lnkDelete _Click - this may be an event or a function. Where you define this

I already corrected OnClick="lnkDelete_Click" but still didnt work because I didnt defined "lnkDelete_Click" function.

There is a space in the OnClick="lnkDelete _Click". attributes as pointed out by other member. Should be OnClick="lnkDelete_Click".

There is a space in OnClick="lnkDelete _Click". You need to change it to OnClick="lnkDelete_Click". This would resolve the error.

Hi, You are doing wrong in this line . OnClick="lnkDelete _Click" here you should bind some values like. OnClick="lnkDelete _Click('')"
