i use datalist and item command event is not fire in vb
My aspx code like
<asp:DataList ID="DataList1" runat="server" RepeatColumns="2" RepeatDirection="Horizontal" OnItemCommand="DataList1_ItemCommand"
Width="100%" EnableViewState="true" >
<ItemStyle VerticalAlign="Top" Width="50%" />
<ItemTemplate>
[Code] .....
This is my Datalist control with an image button in footer. I am just pasting the declaration and footer template
[Code]....
And this is my CB:
[Code]....
When I click the button image residing in footer template i just posts back and don't go to the itemcommand event.
I have a checkbox inside the item template of a datalist, dtlLate. I want to detect the checkbox change and execute a stored procedure. When I click the checkbox a postback does occur but the dtl Late itemcommand doesn't fire. I am not rebinding the datalist on postback. I have tried with viewstate enabled and disabled. I have used Bold text for the dtlLate in the content page and in the codebehind to make it easy to find.
[Code]....
I put it down for a few weeks to work on other things, but started working on it again because I need to get it to work.
Anyway, I figured if I wanted to put a button in a datalist all I had to do was:
[Code]....
And then in code behind:
protected void datalist1_ItemCommand(object source, DataListCommandEventArgs e)
{
if (e.CommandName == "submit")
{
// code here
}
}
This is what everyone else says to do when I search google. I put a break on the event but the event never fires. Does it matter if I am using VS 2010 and .net 4.0?
The postback occurs, but the event doesn't fire.

I'm building a navigationmenu and for that I create repeatercontrol dynamicly from codebehind. This works fine with the exception that the ItemCommand event is not firing. The ItemDataBound-event I bind to the repeater-control is working fine. Can somehow tell me what I'm doing from.
Code ASPX
<div id="subnavigation">
<asp:PlaceHolder ID="phControl" runat="server"></asp:PlaceHolder>
</div>

[URL] how to handle item command event in above example?
View 1 RepliesI 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).
I have a ListView that is managing a link click event through the OnItemCommand and the list pages the data.
<asp:ListView
runat="server"
ID="lvRequests"
ItemPlaceholderID="litPlaceHolder"
OnItemCommand="lvRequests_ItemCommand"
DataSourceID="odsResults"
OnItemDataBound="lvRequests_ItemDataBound">

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?
I am upgrading a website project from asp.net 3.5 to 4.0. I went through the upgrade wizard and site compiled and built fine. But immediately I have encountetred a problem.I have 3 nested ListViews all using the ItemCommand event. Under 4.0 once the ItemCommand event has fired on the inner ListView it then bubbles up and fires on the parent and finally the grandparent.This is a change in behaviour from 3.5 where only the inner ListView event fires. While I can code round this I am worried about these subtly changes between the two versions.
View 1 RepliesI have a User Control that contains a ListView. In the user control's code is this event handler:
protected void listView1_ItemCommand(object source, ListViewCommandEventArgs e)
{
Button_ClickHandler(source, e);
}
What's occurring is that I'm explicitly firing an event so that the parent web page can monitor this and take appropriate actions. Thus when the user clicks on a different ListViewItem it triggers the population of associated data elsewhere on the web page.
This all works fine except for one thing: When I first load the control I'm pre-setting the first ListViewItem. Unfortunately, just setting the ListView's SelectedIndex = 0 doesn't fire the aforementioned event handler.
So I started investigating how to call "listView1_ItemCommand" but couldn't figure out how to instantiate the "e" parameter.
I have a formview and a few buttons outside the formview. How can i access the formview.itemcommand event if the buttons are not in the formview?
View 9 RepliesI am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.
View 3 RepliesI have a datalist inside of an updatePanel. Within the datalist, for each item I have a linkbutton that when clicked I would like to fire the OnDeleteCommand of the datalist so that I can delete the record.
Problem is that I can never get the event to fire, it simply does a postback and then does not fire the event specified inthe "OnDeleteCommand" argument of the datalist control.
I've read many postings with similar entries, but nothing has worked.
I have the same animationExtender that I want it come in whenever the user clicks on any of the items on the datalist, so how can I set that?

Very new to ASP.NET (using C# behind) and am having trouble figuring out the following scenario. I have a DataList that is populated (code below) and wanted each cell to be clickable. When the cell is clicked I wanted to know the unique ID for that cell. In my code behind, my OnClick method looks like this:
[Code]....
However I never get there. It seems as if the linkbutton always refers to some javascript callback function and just reloads my form. Am I using the wrong control for what I want to do? From this click I want to look up more information from the Key (will roll up the datalist or set visible to false, then supply the new data on the same page)DataList:
[Code]....
<asp:DataList ID="listSearchResults" Border="1" BorderColor="Black"
i wrote the following code to perfrom the inline deletion of datagrid elements.

the row deleted event is not firing and the row deleting event is firing twice. why is is happening?

View 8 RepliesThe <ItemTemplate> loads properly, and the line:

The method SetPage_N_of_All is in the codebehind page and is as follows:

I am using a calendar extender which is an Ajax control I am selecting a date but the event is not fired.
The reason I am doing this is because I am setting an expiry date based on the date selection.
<asp:TextBox ID="start_date" Width = "165px" Height = "24px" runat="server" OnTextChanged="start_date_click"
></asp:TextBox>
<asp:TextBoxWatermarkExtender ID="TextBoxWatermarkExtender1" Enabled="true" TargetControlID ="start_date" WatermarkText="Start date" runat="server">
</asp:TextBoxWatermarkExtender> <asp:CalendarExtender ID="CalendarExtender1" Enabled="true" runat="server" TargetControlID ="start_date" >
</asp:CalendarExtender>
The code behind
protected void start_date_click(object sender, EventArgs e){
DateTime begindate = DateTime.Parse(start_date.Text);
exirydate.Value = Convert.ToString(begindate.AddDays(days));
}
Is my codebehind code correct. Am i not doing in a right way.
