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
View 1 RepliesI 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:

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.

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...

the 'updateorderdetails' event in code behind is here
Public Sub UpdateOrderDetails(ByVal s As Object, ByVal e As RepeaterCommandEventArgs)
For Each objRepeaterItem As RepeaterItem In rptOrderDetails.Items
Select Case objRepeaterItem.ItemType
Case ListItemType.AlternatingItem, ListItemType.Item
Dim chkDelete As CheckBox = objRepeaterItem.FindControl("chkDelete")
Dim hidProduct_Key As HiddenField = objRepeaterItem.FindControl("hidProduct_Key")
Dim txtQuantity As TextBox = objRepeaterItem.FindControl("txtQuantity")
' check for deletion or update
If chkDelete.Checked Then
Me.Basket.RemoveProduct(hidProduct_Key.Value)
Else
' check for update
If IsNumeric(txtQuantity.Text) AndAlso CInt(txtQuantity.Text) >= 0 Then
Me.Basket.Products(hidProduct_Key.Value).Quantity = txtQuantity.Text
End If
End If
End Select
Next
' update order details
BindOrderDetails()
End Sub
but this procedure is never called when the button is clicked, so wondered what i need to do to get this working

[URL] how to handle item command event in above example?
View 1 RepliesI'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?
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?
In my project when i click any button or linkbutton, it doesnt fire any event or doesnt postback.
It was working fine but now it hv problem like this.
I think i have changed some settings by mistake.
I have added the AutoPostBack = "true" attribute to the drop down list. It doesn't work.
<asp:DropDownList CssClass="dropDownList" ID="ddlBusinessUnit"
AutoPostBack="true" runat="server" Width="250px"
OnSelectedIndexChanged="ddlBusinessUnit_SelectedIndexChanged">
</asp:DropDownList>
code behind:
Protected Sub ddlBusinessUnit_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
Response.Write("Hello")
End
How can I ensure that the event method is called?

TextBox doesn't fire TextChanged Event on IE 8, AutoPostback is true
View 6 RepliesI have my ReorderList setup, and it seems to work. It doesn't give me any errors, and it allows drag/drop of the entries.
BUT, it never updates my datasource. I have tried putting breakpoints on the update events, both on the reorder list, but also on the datasource, none fires.
What could i possibly do wrong, to achieve this?
Here's my code, just in case:
[Code]....
[Code]....
I have a small website where I want to display a confirmation dialog after clicking on a button.
When you click the confirmButton the dialog appears. Then you can choose between Yes or No to either continue with the PostBack or to return.
Problem: The first time you get into the site all works fine. But after you click Yes to continue with the PostBack, no click event will be triggered anymore.
Here is some code.
[Code]....
I have an repeater with two buttons. I tried two different ways to make a click event on the two buttons. Neither of the two ways function. They do both the same. No errors but the repeaters content disappear.
My repeater:
[Code]....
As you can see, onbtnForumGroupsDebateListEditDebateAdm I tried to use the repeaters ItemCommand
the code for this here:
[Code]....
Then I tried to do a simple OnCommand instead
The code for this is:
[Code]....
I tried to make a "run to curser" and can see, that I don't get into the functions.
I create a dropDownList in code-behind, in selectIndexChange of another dropDownList, and add this new dropDownList to page using a placerHolder, everthing its ok, but new dropdownlist selectIndexChange event dont fire!
code of dropDownList creation
dropDown = new DropDownList();
dropDown.AutoPostBack = true;
dropDown.ID = idSubistema;
dropDown.Width = 400;
dropDown.CssClass = "controltext";
dropDown.DataValueField = "IDNivel";
dropDown.DataTextField = "NIVEL";
dropDown.EnableViewState = true;
dropDown.DataSource =
DBLibray.DefinitionIndicadores.spSelect_FillCombosWithNivelByIdParent(
ref dataConnector,
Convert.ToInt32(idSubistema));
dropDown.DataBind();
dropDown.SelectedIndexChanged += new EventHandler(indexChange);
//dropDown.PreRender += new EventHandler(dropDown_PreRender);
placeHolderForCombos.Controls.Add(new LiteralControl("<div>"));
placeHolderForCombos.Controls.Add(lb);
placeHolderForCombos.Controls.Add(new LiteralControl("<br>"));
placeHolderForCombos.Controls.Add(dropDown);
placeHolderForCombos.Controls.Add(new LiteralControl("</div>"));
placeHolderForCombos.Controls.Add(new LiteralControl("<br>"));
A little confused on something. I have a User Control in a master page. In the User Control there are image buttons. when I try to wire any click event even to say update a label in the User Control itself, nothing gets updated.
It is as if the postback is not handled at all.
What I want to do is click the image button in the User Control and then change a value in the master page. This could happen a few ways but for example it could update a public property or a control itself like a textbox or label.
Here is my situation: I have a overview of subscriptions that look simple:
Active (bool), ID (int), StartDate (datetime) and MaxUsers (int).
I've put this in a Gridview and it renders nicely.
Now everything is simply in ItemTemplates and are formatted.
Now a new feature: In the Gridview active should be a checkbox and when clicked on it, it should (de)activate the subscription. Or simply said, Active status is updated. Now me being a simpleton thinks:
[Code]....
and the cs:
[Code]....
But! the event doesnt get fired. Now I've searched with google and also through this forum and every time I get the answer: autopostback on true or use commandname. Now for this little feature I think the commandname use in combi with rowbound is overkill for such a little thing.
Now I hope I'm just missing something because this would be really nasty and stupid to make it so complicated. I like the autopostback and oncheckchanged combination because it logical, but why doesnt it work?
I have a modalpopup that i have opening on a radiobutton selection. That works great, opens when it should and closes when you click cancel. BUT i have the following on my cancel button event that is not firing
[Code]....
I also have a button event for my "OK" button and that works great, but my cancel event doesnt seem to fire or work. Maybe the ClearSelection() is not what i need..
I want to clear the radiobutton if they cancel out of the ModalPopUp so they can make a new selection, since its a required field.
how do i fire the itemdatabound event for a repeater control which is nested inside a another repeater control
code is in vb.net
I have imagebutton inside datalist.....the problem is that onclick event of serverside not get executed for only IE ..but its work fine for mozzila....i m not getting what wrong in this code.aspx code
