IpInterfaceUC UserControl
<div id="dvChannel" runat="server">
<asp:GridView ID="gvChannelUC"
OnRowCommand="gvChannelUC_RowCommand"
OnSelectedIndexChanged="gvChannel_SelectedIndexChanged"
/>
</div>
IPServices page CodeBehind
if (!IsPostBack){
}else
{
string str_btn = Request.Form.Keys[Request.Form.Keys.Count - 1].ToString();
handleClick(str_btn);
}
Question
It always show str_btn is null.If I click Button,It'll show button's id.But when I click Select at GridView,It show str_btn is null.It should be show GridView's id when we click select.
Thanks for any explain.
Try giving name
attribute to your gridview,ie name="yourGridName"
.
<div id="dvChannel" runat="server" name="yourGridName">
<asp:GridView ID="gvChannelUC" name="yourGridName"
OnRowCommand="gvChannelUC_RowCommand"
OnSelectedIndexChanged="gvChannel_SelectedIndexChanged"
/>
</div>
As per my understanding you need grid event handing (.ascx) on page/codebehind (.aspx).
declare eventhandler in userControl
public event EventHandler<EventArgs> RaiseSelectedIndexChanged=delegate {};
handle userControl selectedindexchanged event in userControl.cs
protected void gvChannel_SelectedIndexChanged(object sender, EventArgs e)
{
var raiseSelectedIndexChanged = RaiseSelectedIndexChanged ;
if(raiseSelectedIndexChanged!=null)
{
raiseSelectedIndexChanged(sender, e);
}
}
register and use your userControl in aspx (which I hope you already did) this code will go in aspx page
<uc:userControl OnRaiseSelectedIndexChanged="OnRaiseSelectedIndexChanged"/>
handle the event in aspx code behind
protected void OnRaiseSelectedIndexChanged(object sender, EventArgs e)
{
//handle your event and put logic
}
I hope i make it clear , let me know if it confuses you.
