.NET Forum / ASP.NET / General / June 2007Accessign System.Web.UI.WebControls.Repeater in code
I have a Repeater control in an app I'm updating. I need to write code (event method) when a user clicks on one of the columns in the control. But there is no method like "Repeater_OnClick" or something like that. Is there a way to get access to this control with an event method of some kind? If not, (and here's where my inexperience in web development will show through), is there another server side grid type control that I could switch to? I would prefer not to do this as there is a lot of other code (in javascript, etc) that is tied to this control but if I have no choice I'm not sure which is the best to use. > I have a Repeater control in an app I'm updating.

I am not sure of exactly what problem you are referring ... But if the problem is catching repeater's click event in server side... then try itemCommand event of reapeater... and use e.commandname e.commandsource etc... to solve your problem Thanks Masudur Hi Masudur, I put some code in the itemCommand event for my repeater, put a breakpoint on that code, clicked on the grid when I ran the app and nothing happened. What action causes the itemCommand event to be executed? > Hi Masudur, > > I put some code in the itemCommand event for my repeater, put a > breakpoint on that code, clicked on the grid when I ran the app and > nothing happened.

I am not sure what is going on there... here how it should go... <asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1" OnItemCommand="Repeater1_ItemCommand1"> you put some kind of button or link button .... in itemTemplate or AlternetingItemTemplete for example <ItemTemplate> <div style="background-color:#cccccc"> <asp:Button ID="btnSelect" Text="Select" runat="server" CommandName="Select" /> <asp:Label ID="lblName" runat="server" Text=<%# DataBinder.Eval(Container.DataItem, "Name") %>></asp:Label> </div> </ItemTemplate> as you can see in commandName property of the button i put "Select" As the command name after that in codebehind file protected void Repeater1_ItemCommand1(object source, RepeaterCommandEventArgs e) { if (e.CommandName == "Select") { //do some code... } } i think i didn't understand what the actual problem is ... can you be a little bit more descriptive. Thanks Masudur http://munnacs.110mb.com Well, the problem has kind of changed. Here's an example of what my repeater looks like in html (this is a partial example for space sake): <asp:repeater ID="RptTrip" Runat="server" EnableViewState="false"> <ItemTemplate> <trip_detail_info trip_detail_id ='<%# Container.DataItem("trip_detail_id")%>' leg_start_dt = '<%# Container.DataItem("leg_start_dt")%>' /> </ItemTemplate> </asp:repeater> This grid is tied to an xsl document. I would like to set this up so that I can write a method in VB.NET to access the data in this control. At this point, I don't need a Repeater control event anymore, I have a button that I've created - outside of the control - that will have code behind it to do the work I need. But I need to know what the data is inside the control. The Repeater control appears to have no properties/methods, etc of any kind that will show me what data is inside of it as far as I can tell. So I can't figure out how to "read my data". I am thinking that somehow I need to read the xsl but am not sure there either. At this point, I am not sure what the best approach is to accomplish this. > Well, the problem has kind of changed. > [quoted text clipped - 24 lines] > there either. At this point, I am not sure what the best approach is > to accomplish this. hi... First can you please make sure that your View state persists... by enableViewState = true... foreach(RepeaterItem item in Repeater1.Items) { if (item.ItemType == ListItemType.AlternatingItem || item.ItemType == ListItemType.Item) { Label lbl = (Label)item.FindControl("lblName"); if (lbl != null) { string Name = lbl.Text.Trim(); } } } Thanks Masudur www.kaz.com.bd http://munnacs.110mb.com Hi Masudur, I found a way around my issue. It wasn't exactly what I planned on doing, I stored the data I needed to access from the repeater grid inside a hidden control and used that to do what I need. Since I won't ever be using much data at any given time, this seems to work well (and gets me around a problem that has been taking days to figure out!)
