C# - LinkButtons Created Dynamically In A Repeater Don't Fire ItemCommand Event

Jun 2, 2010

I've got a repeater that's used to display the output of a dynamic report that takes criteria from webcontrols on the page. Within the repeater's ItemDataBound method I'm adding controls (Linkbuttons for sorting by column values) dynamically to the header of the repeater based on values selected in a checkbox list and at this point setting the CommandArgument and CommandName properties of the linkbuttons.

The issue is that when the linkbuttons are clicked they don't fire the ItemCommand event although they are clearly being correctly created and added to the header (there is some additional code to set the cssClass, text etc. and this works as expected.) The first column header in the repeater is set in the markup and the itemcommand event fires correctly on this one only. When the other column headers are clicked the repeater rebinds as programmed, but the columns are not dynamically re-generated.

Nightmare.ascx
<asp:repeater runat="server" id="rptReport" OnItemDataBound="rptResults_ItemDataBound" OnItemCommand="rptResults_ItemCommand" EnableViewState="true">
<headertemplate>
<table>
<tr runat="Server" id="TRDynamicHeader">
<th>
<!-- This one works -->
<asp:Linkbutton runat="server" CommandName="sort" commandArgument='<%# Eval("Name")%?' />
</th>
<!-- additional header cells get added dynamically here -->
</tr>
</headertemplate>
<itemTemplate>
<td><%# Eval("Name")</td>
...
</itemTemplate>
</asp:repeater>
Nightmare.ascx.cs
protected void PageLoad(object sender, eventArgs e){
if (! isPostback){
setupGui();//just binds dropdowns etc. to datasources
}
}
protected void btnRunReport_Click(...){
List<ReportLines> lstRep = GetReportLines();
rptReport.DataSource = lstRep;
repReport.DataBind();
}
protected void rptReport_ItemDataBound (...){
if (e.Item.ItemType == ListItemType.Header)
{
foreach (ListItem li in chbxListBusFuncs.Items)
{
if (li.Selected)
{
th = new HtmlTableCell();
lb = new LinkButton();
lb.CssClass = "SortColHeader";
lb.CommandArgument = li.Text.Replace(" ", "");
lb.CommandName = "sort";
lb.Text = li.Text;
th.Controls.Add(lb);
((HtmlTableRow)e.Item.FindControl("TRDynamicHeader")).Cells.Add(th);
}
}
}
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
//Row level customisations, totals calculations etc.
}
}
<!-- this only gets called when the 'hardcoded' linkbutton in the markup is clicked.
protected void rptReport_ItemCommand(object sender, Eventargs e){
lblDebug.Text = string.Format("Well? What's Happening? -> {0}:{1}", e.CommandName, e.CommandArgument.ToString());
}
(The only thing that can call the runreport routine is a single button on the page, not shown in the code snippet above.)</textarea></p>

I have a page with a couple of RequiredFieldValidators, each in its own ValidationGroup. One of the RequiredFieldValidator controls is inside a Datalist and the submit button triggers the relevant DataList_ItemCommand. It works just dandy until I add the ValidationGroup to the button, at which point clicking on the button no longer fires the DataList_ItemCommand event. Here is the HTML

[Code]....

Note that the ValidationGroup name is there, and it is unique. No other ValidationGroups exist with that name. As it stands, this code does NOT fire the DataList_ItemCommand event, so no update occurs. However if I remove the ValidationGroup declaration from the Button control, the event fires properly.

i have a repeater with a button in the footer template which i want to be able to update any of the items that are added (update quantites/totals/delete the item). however the 'UpdateOrderDetails' event never fires when the button is clicked. here is the code within the repeater...

Repeater Doesn't Fire ItemCommand Event

Oct 11, 2010

My repeater is available in a user control and I added the user control as a web part to an existing webpartzone. I could see all rows in the repeater (along with buttons). Once I click the (any) button, it loses all the rows and itemcommand never fires. I am using ASP.NET 4.0

C# - ItemCommand Event Doesn't Fire With The Repeater Control?

Feb 21, 2011

I am building a website whereby people, before checking out of the shopping cart (and transferring to the payment iframe) can select which items from the shopping cart list to delete. The results from the shopping card are listed in a Repeater control. There is a Button in the Repeater which deletes a record from the database (used LINQ to SQL to do that.)

THe problem is that the ItemCommand event doesn't fire when i click the button. I tried 'response.write(test)' and it still would not work. It is as if the repeater cannot interact with the commands. It does render the results tho.

Here's the code:

C# - Button In A Repeater Does Not Fire ItemCommand

Web Forms :: Dynamically Created Control Does Not Fire An Event?

Jul 8, 2010

I'm creating some linkbuttons dynamically and assigning properties like below. Also I'm adding an event handler to the created link button:

[Code]....

What happens here is when the links created at runtime are clicked, most of the links are linked to other applications. (e.g from app1 to app2, app1 to app3 etc..) So when moving from the current app to the next I want to abandon the current session. However, this event is not firing before navigating to the next page. Could someone suggest a workaraound or the correct way to accomplish that?

Web Forms :: Dynamically Added LinkButtons Won't Fire

Feb 9, 2011

I've been struggling with this for several hours now so I thought I'd give this forum a try. The problem is that I'm adding two kind of buttons (editBtn and delBtn) which show up fine but they won't fire their respective method when clicked. I also have a third button which works just fine.

Forms Data Controls :: Manually Fire A GridView ItemCommand Event?

Mar 19, 2010

I've got a GridView control with LinkButtons in different cells. Currently when someone clicks a link, it fires the ItemCommand passing the CommandName and the ID of the item the link is bound to. That all works fine. I need to modify it now to not use links anymore. It now needs to show a popup balloon with a link (styled to look like a button) and when the link is clicked, I want it to do the exact same thing. I'm sure there are several ways of doing this, but for time's and consistency's sake, I'm copying the method used from another page we have that is already doing this. It has a hidden DIV on the page with the link in it. When you hover over a link, javascript repositions the div and makes it visible.

So what I need to do is pass my CommandName and item ID to the javascript so that it can trigger the postback when they click that single link. I know this is not the only way to get to the end result, but what I want to do if possible, is still fire the GridView's ItemCommand and set he DataListCommandEventArgs' CommandName and CommandArgument properties. Can someone explain how, under normal circumstances, clicking the LinkButton in the GridView fires the ItemCommand? I know that the LinkButton's click event is forwarded to the GridView but what gets sent from the client side that let's the server know the link was clicked?

C# - How To Access ItemTemplate Control From ItemCommand Event Using Repeater

Nov 26, 2010

My repeater:

<asp:Repeater ID="rptrContacts" runat="server" OnItemCommand="rptrContact_ItemCommand" >
<div ID="itemTemplate>
<ItemTemplate>
<%# Eval("Name") %>
<%# Eval("Email") %>
<asp:LinkButton ID="lbtnEditContact" runat="server" CommandName="Edit" Text="Edit" CommandArgument='<%# Eval("ContactID") %>' />
<asp:Label ID="lblUpdateConfirm" runat="server" Text="Update Confirmed" Visible="false" />
</ItemTemplate>
</div>
<div ID="editTemplate runat="server" visibility="false">
Update your Info:<br>
Name: <asp:TextBox ID="txtName" runat="server Text="<%# Eval("Name") %>"/> <br>
Email: <asp:TextBox ID="txtEmail" runat="server Text="<%# Eval("Email") %>"/><br>
<asp:LinkButton ID="lbtnUpdateContact" CommandArgument='<%# Eval("ContactID") %>' CommandName="UpdateContact" runat="server" >Update</asp:LinkButton>
</div>
</asp:Repeater

and code for ItemCommand:

switch(e.CommandName)
{
case "Edit":
//make editTemplate div visible
HtmlGenericControl divEditContact = (HtmlGenericControl)e.Item.FindControl ("divEditContact");
divEditContact.Visible = true;
break;
case "Update":
Employee updateEmployee = new Employee
{
employeeName = txtName.Text:
employeeEmail = txtEmail.Text:
}
updateEmployee = API.UpdateEmployee(updateEmployee);
//display lblUpdateConfirm visible to True
// so user sees this confirm messge in the newly updated ItemTemplate
}

How can I access my lblUpdateConfirm and turn its Text state to visible from inside the ItemCommand, so that when the user sees the newly updated ITemTemplate, the label is showing the "Update Confirmed" message?

Web Forms :: Programmatically Created Event Handler For A Button Doesn't Fire Up?

Mar 21, 2010

I'm trying to manually create a button and add a Click event handler for it in code. However when the button is clicked the event handler doesn't seem to react on event (or event isn't called).

we tested the code in Visual Studio 2008 and everything worked just as it should. And I'm using Visual Web Developer 2005 XE. So I assume that I'm missing something to be done manually being in VWD 2005 XE, or the problem is in VWD 2005 XE it self.

here is what I'm doing:

Forms Data Controls :: Buttons In Repeater Don't Fire Event?

May 13, 2010

My repeater:

As you can see, onbtnForumGroupsDebateListEditDebateAdm I tried to use the repeaters ItemCommand

the code for this here:

Then I tried to do a simple OnCommand instead

The code for this is:

I tried to make a "run to curser" and can see, that I don't get into the functions.

Forms Data Controls :: Dynamically Created Repeater Control

Dec 1, 2010

What I am trying to achieve:I am trying to take the value of the selected index and depending on what this value is (e.g. the case selection in the code below) run a different query on the dataset and then create a repeater control dynamically to output each row with an item template
that I can use css to style.

In other words: When a user choses a list item it shows only rows from the dataset that match the list item chosen. For example if a user choses Closed Tickets they only see rows from the dataset that have a STATUS of 'CLOSED'.

What I have done so far: [Code]....

What I'm struggling with at the moment is:

1) That the case selection works but the selection of the appropriate data from the dataset doesn't seem to be happening. And this data isn't getting stored in rows as I had hoped.

2) I'm not sure entirely how to display the dynamically created repeater control in the admin.aspx page.

C# - Recursively Extract Dynamically Created Controls In A Repeater, Part II?

Dec 16, 2010

To be fair, this is a part two follow up to Using C# to recursively get a collection of controls from a controlcollection. - and rather than heap another question onto the old one, I created a new one. Here is the code that I'm using:

private void GetControlList<T>(ControlCollection controlCollection, ref List<T> resultCollection) where T : Control
{
foreach (Control control in controlCollection) [code]...

and is involked like this when the form is submitted

List<CheckBox> checkboxes = new List<CheckBox>();
GetControlList(RepeaterCapability.Controls, ref checkboxes);

I don't get any results when I clearly added several during the repeater OnItemDataBound event.

Forms Data Controls :: Entire Row Of DataList To Fire ItemCommand - Got It In IE But Not FF

Oct 12, 2010

I have a datalist in my page that has a LinkButton at the beginning of each row that, when clicked, fires the Itemcommand ("select"). There is no issue with this as it works as it should:

[Code]....

But I also thought it would be good if the user could simply click anywhere in the datalist to expand the item and show based on the SelectedItemTemplate. So, I thought, the cleanest would be to add a function in the code behind that adds a click event to the Panel "panItem" that clicks the above mentioned LinkButton like this (fires in Page_PreRender):

[Code]....

Here is where the problem comes in. This works great in IE but not FF3.6 (havent tested it with older version of FF). In FF, I get a JS error saying "dlMapDB_ctl00_btnItemFigNumber is not defined" for the first row, "...ctl01..." for the second row, etc. So the IDs are correct based on the markup (which makes sense since it works in IE).

Repeater Not Binding After ItemCommand?

Oct 29, 2010

I have a repeater that is looping a user control, like this:

<asp:Repeater ID="repItems" runat="server" EnableViewState="false"
OnItemCommand="repItems_ItemCommand">
<ItemTemplate>
<dmg:confirmItem runat="server"

[Code]....

All works brilliantly the first time around, the basket items are bound to Basket objects and everything is great.

However, when I receive an ItemCommand from my repeater, and update the basket contents (Note: No adding or removing is done here, just updates the quantity) then I rebind to see the latest values, and BOOM! Null reference - no Basket object in the user control Page_Load. This is despite tracing through to see that the BindItems() method is called as usual, and the Baskets are there.
