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?

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:

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# - 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.

Forms Data Controls :: How To Access Attributeid Values In Repeater Control's ItemDataBound Event Handler

Jan 15, 2011

i have simple repeater control on my page:

<asp:Repeater id="Repeater1" runat="server" DataSourceID="SqlDataSource1">
<ItemTemplate>
<asp:TextBox id="txtBox1" runat="server" Text='<%#Eval("attributename") %>'></TextBox>
<ItemTemplate>
</Repeater>

I'm bounding data to repeater control by using SqlDataSource Control

bounded data is something like this:

attributeid attributename
1 color
2 size

How can I get access to attributeid values in Repeater control's ItemDataBound event handler,

I tried to use DataBinder.GetPropertyValue(container,"attribuetid"), but I can't set container, am I doing right, or maybe I should use another approach.

Setting ID To A Control Inside Repeater Itemtemplate?

Apr 1, 2010

Inside repeater's itemtemplate I have a Panel server control.I need to assign special Id for it, because I need to work with some javascript functions that use this Id.

In repeater ItemDataBound event I have this:

pnlButtonsPanel.ID = pnlButtonsPanel.ID + DataBinder.Eval(e.Item.DataItem, "ID");

But this solution is not good because after a postback the page is re -rendered and I lose the new ID. (And I don't want to rebind repeater after every postback)

I tried to set the ID on aspx page like that:

<asp:Panel id='<%# Eval("ID") %>'

and some other variations but always get compile errors.

Forms Data Controls :: How To Alter A Control In A Repeater's ItemTemplate From A Handler

Mar 27, 2010

I have a repeater bound to a datasource that servers as a list of birds. When the user clicks an item in the list the bird's image is displayed on the page. I want to change the background color of the item that is currently selected in the OnClick handler for the main item in my repeater's ItemTemplate.

I have changed the styling of controls prgrammatically before and it worked fine but in those cases i used the ID of the control to directly access it in my code behind file. But since this is some arbitrary item in a repeater I don't know it's ID at runtime, all I have is the sender object passed to the control's OnClick handler. So in my code behind file, I tried casting the sender object passed to the OnClick handler to the appropriate type and used Style.Add("background-color", highlitColor) but it failed to change anything.

I had a thought - maybe this sender object gets passed by value so all I did was change the Style of a COPY of the control item.

If this is indeed my problem, how do I start with a casted sender object in an event handler and get a reference to the actual control in order to change it's Style?

AJAX :: Repeater Data Server Control Has HTMLEditor Inside Is ItemTemplate?

Jun 20, 2010

I am having big trouble with this issue, getting a message from IE that a script is being running for a long time and asking me to stop it myself.

The HTMLEditor seems to be uncomptible with this one.

I am also getting a very weak performance when adding this Ajax control.

I think this control is very heavy, but I'm not sure. If I am not wrong, this post I'm writing is inside the same control and I can see it takes time to load it in my page.

Data Controls :: Export Repeater Control With TextBox In ItemTemplate To Excel

Jul 17, 2015

I have a repeater control that is getting exported to excel. Well excel will no longer show the data that was in the textboxes. I've read the article on exporting a gridview having the same problem and how you replace the texboxes with literal contrls. I was wondering if there is an article like it only for a repeater control.

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.

Forms Data Controls :: How To Avoid Repeater Databind On ItemCommand

Apr 3, 2010

I have a repeater which does quite expensive processing when it is populated. It gets the info from a web service which is itself a federated search service and will take 15 to 20 seconds to return results.

In each repeater item/alternatingitem, i have 3 imagebuttons doing some actions (saving in session some ID's, updating some custom collections...) , the problem is when clicking on one of the buttons, the repeater will trigger the command and then databind again, which takes quite some time to process again..

Forms Data Controls :: Switch FormView To Edit Mode From Repeater ItemCommand?

Sep 30, 2010

The following code successfully displays a record in a FormView and sets the FormView mode to 'Edit' when the user clicks on a LinkButton within a Repeater, however the record is not Updated. If I don't change the .SelectCommand and call .DataBind, I'm able to update the first record that is displayed. Naturally that's a moot point because the idea is to be able to update the record that the user selects in the Repeater.Because of the design of the FormView and Repeater, the record *must* be updated via the FormView. Updating the record via the Repeater is not an option.

Jquery - Secondary Repeater W/ ObjectDataSource Databind Event Fired From Another Repeater's Click Event?

Mar 29, 2011

I'm having trouble managing how to call upon databind from clicking on a row over an already populated repeater that will populate data regarding the row clicked TO another repeater on the same page.

I've succeeded doing that with postback, calling a jquery click event of that row, taking the data of the specific row and passing it onto a "Querystring" and after postpack, it will be pushed into a Session which the ObjectDataSource of the secondary repeater will recognize and populate the data tables accordingly.

The problem is, I must do it without a postback or in other words purely on client side.
