在ASP.NET GridView控件中未触发按钮单击事件

Question

 <asp:GridView ID="gvInaciveQuestions" runat="server" AutoGenerateColumns="False" OnRowCommand="gvInaciveQuestions_RowCommand">
            <Columns>
                <asp:TemplateField HeaderText="Selelct">
                        <ItemTemplate>
                            <asp:Button ID="btnactive" runat="server"  Text="Active" onClick="btnactive_Click" />
                        </ItemTemplate>
                    </asp:TemplateField>                   
                <asp:TemplateField HeaderText="Question">
 </asp:Gridview>

I have added Itemtemplate as Button but it is not firing onclick event.

Could please any one suggest me ?

Answer 1

Don't DataBind it on every postback by using the Page.IsPostBack property, for example in Page_Load (resuming that the method that you're using for databinding is called BindGridView ):

protected void Page_Load(ovject sender, EventArgs e)
{
    if(!IsPostBack)
    {
        BindGridView();
    }
}

Otherwise events aren't triggered and changed values in the grid are overwritten by the values from your (old) DataSource .

Answer 2

you should not use onClick="btnactive_Click" event here, instead use CommandName property.

<asp:Button ID="btnactive" runat="server"  Text="Active" CommandName="Click" />

In your OnRowCommand in codebehind implement like this.

 protected void gvInaciveQuestions_RowCommand(object sender, GridViewCommandEventArgs e)
            {
                if (e.CommandName == "Click")
                {
                  //your code here
                }
            }

I hope this will solve your issue.
