View 3 RepliesWe have a function that changes the iframe height at the window.onload event so we can adjust it to the page contents. The problem is that after clicking in an asp:menu the height its restored to its default and the window.onload event doesnt fire...so we need the event that would fire in subsequent loads (tried window.unload but didnt trigger)
The resize function cant be called on the asp:menu click because the window wouldnt have finished loading so the height calculation would fail...
I have the following download request in javascript:
var exportWindow = window.open('Download.ashx?source=1', '');
exportWindow.onload = function() {
alert('finished');
};
My problem is that the above alert box does not appear. The download.ashx sets up the following response (which will be saved as a csv file), which works fine.
context.Response.ClearContent();
context.Response.ContentType = "application/text";
context.Response.AddHeader("content-disposition", "attachment; filename="" + fileName + """);
context.Response.Write(resultWriter.ToString());
context.Response.Flush();
context.Response.Close();
If I replace the download.ashx with a normal aspx page, then the alert appears. So my question would be: is it possible to know programatically when the dowload.ashx returned with a response?(using FF3)
We are writing a portal and like every portal we store html data in Db fro Modules. So I thought that I can cache each module in files. I use OnLoad event to check if there is a cache file for this Module, use that and else create cache file:
if (!IsPostBack)
{
string Path = AppDomain.CurrentDomain.BaseDirectory + "CacheModules" + ModuleId + ".dat";
if (File.Exists(Path))
{
Controls.Clear();........

View 3 RepliesI would like to create a gridview that gets data from a datasource but doesn't display it in the normal fashion based on my table layout.
Example:
Table layout is:
Name Emp# Dept# Booking Code# AccessId
This is how it looks in the gridview but I would like it to look like:
Name: John Doe Dept#: 12
Booking Code#: 1234 Booking Code#: 67
AccessId: 33
What data object will give this?Gridview won't work I think.
I have a dropdownlist outside the gridview control. My griview control also have dropdownlist in the first column. I want to populate the dropdownlist inside the gridview control for all rows when the selected item is changed in the outside dropdownlist.
View 2 RepliesI have a gridview with several ItemTemplates. The first contains a checkbox the rest contain textboxes. I then added dynamically some bound controls like this:
BoundField bdfPrivName = new BoundField();
clsUtilities.SetBoundFieldCenter(ref bdfPrivName, "PrivName", "Priv Name");
BoundField bdfDescription = new BoundField();
clsUtilities.SetBoundFieldLeft(ref bdfDescription, "PrivDesc", "Description");
BoundField bdfLive = new BoundField();
clsUtilities.SetBoundFieldCenter(ref bdfLive, "Live","Active?");
grdExisting.Columns.Add(bdfPrivName);
grdExisting.Columns.Add(bdfDescription);
grdExisting.Columns.Add(bdfLive);
I then use FindControl to locate the checkbox and textboxes and perform my logic based the result
foreach (GridViewRow gvr in grdMissing.Rows) {
mckbAny = (CheckBox)gvr.FindControl("ckbAdd");
mtxtApplyDate = (TextBox)gvr.FindControl("txtAddApplyDate");
mtxtDateToAdd = (TextBox)gvr.FindControl("txtAddDateToAdd");
mtxtDateToRemove = (TextBox)gvr.FindControl("txtAddDateToRemove");
etc.
This all worked fine. I then got a request to put the bound fields as the second, third and fourth columns, after the check box and before the textboxes. I found that this was easy to do by changing the Add's to Inserts as follows:
grdExisting.Columns.Insert(1, bdfPrivName);
grdExisting.Columns.Insert(2, bdfDescription);
grdExisting.Columns.Insert(3, bdfLive);
It looked fine of the page, but the FindControls, all of them fail to work.
I'm using the code below to extract data from a gridview and populate it into textboxes for the days and two drop downs for Project and Category.
For some rows in the gridview everything but the category ddl populates correctly. If I click the row a second time the category ddl displays the correct category.
why I have to click twice for some rows? And how do I fix this?

View 9 Repliesi have been following the asp.net data access tutorials on this site. When i try to update, nothing happens. I believe the problem lies with my wrong coding on the BLL part. I'm using table adapters. Could anyone point out what iswrong with my code or tell my what the correct code is?

I have a GridView. I allow editing using:
[Code]....
As I allow editing of row, so I have GridView:RowUpdating(). In it, I check if the entered value is valid. If not, I have e.Cancel = true.
[Code]....
After I see the message box comes up, the textbox still stays the same. I expect the textbox will disappear just as if I have pressed the Cancel button. (By the way, the ClientUtil is a class someone has written for me.)
How do I make the e.Cancel = true works as if I press the Cancel button.
Can't tell what is wrong here . It worked fine and I didn't did anything special in code-behind
I don't see any error just the same data in gridview
