I have a databound repeater and in this repeater is an imageButton. How do I pass info from the database into the click event? For example, I've got the description, heading and price fields populating labels, but want the id to go into the imagebuttons click event in order to build a querystring.

I am trying to create a custom GridView with a header toolbar at the top that will contain icons to export the grid view to different formats like excel, word, etc.. The problem is, I cannot get the method to fire that is assigned to handle the click event for the corresponding Image Button. The page posts back, but the code I have in the method to handle the click event does not fire. I have followed examples in other posts and from what I can tell I have followed what others have done. Can somebody take a look at see if they can find something that I am doing wrong.

How to bind repeater with database in click event in asp.net ???
View 1 RepliesI have a user control that displays a shopping cart in an ecommerce application.
The main cart display is a repeater that renders as a html table. In one of those table columns, there is another repeater to display people associated with the products int he cart (it's a repeater in case there is a line item >1 with multiple people).
I've added an ImageButton that I want to use to change the person associated with the item. At first, when I'd click on it I was getting this error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
So as an experiment I disabled EventValidation on the page (not the control it's self) and now I do not get an error, but I also do not ever hit the breakpoint I set in the innermost repeater's ItemCommand event.
So I wonder how I might do this without disabling EventValidation, because this control will show up on multiple pages and we don't want to edit them all. Also, I'll need to know not only the repeater containing the control's row that the event came from but also the row index of the repeater containg this one. Is this possible?
I have a repeater control and in its footer temlate is a button (or 2 in the example) and I want to catch its click event but seem to not be able to.
I tried in the repeater itemcommand event and also I tried defining a subprocedure for the 'occlick' event but neither works..

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.

I know this question has been asked before. But for some reason I can't find the exact answer I need for my problem. My problem is as follows:
I am creating a web page (The one posted is just an easy example) that creates multiple ImageButtons on one page via a loop.I have tried many other ways (for example, create instance in form_load and pass to the WriteHtml() method) but I can't figure out a way to complete this. In this example I have 10 buttons that need to be able to be clicked.
The code is as follows:

I need to utilize about 30 different database values from within a repeater ItemDataBound Event and I am wondering if there is a better way to do it. I am currently exposing them by doing something like this 30 times:

Rather than making 30 declarations, is there a way I can make them all available as short variable names? The variable name could be the same as the field name.
Im working on app that queries another website, and pulls back an xml, I then populate a result panel with ImageButton(s), and time in a click event, when the image is click I want to popup a div box using the jquery ui, that will show more information, about the picture clicked on. however whenever id this this seems to wipe out my results panel(Panel Control) and the div box never appears and as far as I can tell the imagebutton click event never fires. I've tried doing this two ways one with an update panel and again without, I would appreciate any help on this.Im wondering if I'm doing to much long on my search button click, Im wonder if I should just let the post pack handle populating the result panel and ditch the update panel.(and yes my div tag is set to runat server)I'm also up for suggestions maybe there is a better way to do this, I thought creating hidden div tags for each item, and then running javascript for when the image is clicked and showing it that way, However that seems stupid, in my opinion it seems to make more sense to make my div control once and then update the labels inside it on each image click and then show or hide it.
View 1 RepliesOK, been burning up Google and Bing trying to figure out a good solution to this problem, and so far, I feel like I've taken a dive down a rabbit hole - I'm just waiting on the Queen of Hearts and the Mad Hatter to show up. Alice is kinda cute, but unfortunately, she didn't have any good suggestions, either.
Here's the scenario - I have a User Control on a Child Page that has a Master Page assigned. The control is for logging in to the system, so it contains two text boxes, a couple of links to password recovery and registration, and an ImageButton to handle submission of the username/password entered in the text boxes.
Everything works just as expected when the user actually takes the mouse and clicks on the ImageButton control.
Things don't work so well when the user enters a username and password and then presses the Enter/Return key.
While debugging, VS2005 (I know...ugh!) will stop at the LoginButtonClick event, and seems to run the code. Of course, the .Text property of the two input controls was empty, but the Request.Form collection had the values burried within the collection of Keys.
So, a little bit of digging got me to the point where they can login using either the Enter key or clicking on the ImageButton. So, everything seems like it's good, right? Nope, not so fast.
When I enter a username/password combo that's designed to fail authentication, the code will step through setting the error message, etc, but that information never makes it to the point where it's visible to the user.
I'm not seeing any extra postbacks (obvious ones, anyway), but for some reason, when the page goes to redraw when it's in a "failed" state, the notations just simply aren't there.
Below is the code in the User Control that handles the actual authentication routine. All controls, such as the Label with ID "message", are local to the User Control, so I don't think it's a FindControl("message") problem or something similar...just so bizarre that it disappears seeming without reason.

View 1 RepliesSo I followed Scot Mitchell's tutorial from asp.net/learn on adding a checkbox column to be able to select multiple entries and delete them with the click of a button. When I make my selection and click the button it works on the database end, as the desired entries are deleted. However, the entries remain on the page after it reloads. if I refresh the page it's updated properly but I'd like it to automatically update after the button is clicked.
Also, I tried his method for adding check/uncheck all buttons to the top of the gridview and they don't seem to be working either.
Here's the code behinf from the gridview page:
[Code]....
I have a gridview that has a column with an imagebutton. That image button event calls my update procedure and merely updates that records status and when the gridview rebinds, the image changes and is no longer available.Whats happening is if the page is refreshed, the update occurs again. If i add this around the update code, works great the first time, but then any other updates are ignored.. is there anyway to know wether the page was refreshed vs actual imagebutton postback?
if (!IsPostBack)
{
}
Since the update is just setting a flag for that record, on another page that displays those records for a seperate department. IF by chance the first page is still open and the 2nd department resets the flag, if the first page is refreshed, that flag is reset again. so its creating some inconsistant results..
I have an ImageButton setup, where in the OnInit event, I'm setting the Click event
btnJoinNow.Click += new ImageClickEventHandler(btnJoinNow_Click);
On the client-side, I have setup a jQuery click event which is to fire of a hitwise tracking event only when the button is pressed. The problem I'm having is that it seems that the button event is beating the javascript and not tracking. I need to put a pause of 1 sec before the imagebutton event fires server-side. I've tried the following, but always fires. I've also tried e.preventDefault(), but that just stops the postback altogether.
$("input[id$='btnJoinNow']").click(function(e) {
Spots.HitWise();
setTimeout(function(){
}, 5000);
});
EDIT: The only way I could get this to work, was by doing the following:
$("input[id$='btnJoinNow']").click(function(e) {
Spots.HitWise();
setTimeout(function(){
$("input[id$='btnJoinNow']").unbind('click').bind('click', function(e){});
}, 1000);
return false;
});
This then allows enough time for the HitWise event to track, then clears the click event and calls itself again.

I query the database to get the VideoName and VideoURL of the videos held in my database (Videos saved on the file system with their location stored in the database) then bind the query results to a repeater with the following code
protected void Page_Load(object sender, EventArgs e)
{
// Variables declaration
string strConnString = ConfigurationManager.ConnectionStrings["vidConnectionString"].ConnectionString;
SqlConnection sqlConn = new SqlConnection(strConnString);
SqlCommand sqlcmd = new SqlCommand("SELECT [VideoName], [VideoURL] FROM [Video]");
SqlDataReader sqlReader;
sqlConn.Open();
sqlcmd.Connection = sqlConn;
sqlReader = sqlcmd.ExecuteReader();
VideoRepeater.DataSource = sqlReader;
VideoRepeater.DataBind();
sqlConn.Close();
}
and put a hyperlink into the repeater to list all the VideoName's this works fine but I want to pass the VideoURL to the next page I am using NavigateUrl="PlayVideo.aspx?VideoURL='<%# Eval("VideoURL") %>'" but when I try and load the Page I get the error saying The server tag is not well formed. the whole repeater code is
<asp:Repeater ID="VideoRepeater" runat="server" >
<ItemTemplate>
<asp:HyperLink ID="VideoLink" NavigateUrl="PlayVideo.aspx?VideoURL='<%# Eval("VideoURL") %>'" runat="server"><%# Eval("VideoName") %></asp:HyperLink>

I'm sure i've just got the hyperlink navigateURL wrong put not sure how else to pass the VideoURL variable
