This should be simple but I am baffled. I have a perfectly functioning DataGrid that I can click its "Select" link to select any one of its rows. When I do, the row highlights itself in red as expected. So far, so good.I also have an independent Label on the same page and I want to update its Text value to a cell value from the DataGrid when I select a specific row.OTH the DataGrid (named GridView1) and the Label (named Label2) are within an UpdatePanel.PROBLEM: When I select a row from the DataGrid, the Label is not updated with the cell's contents. It simply retains its original default Text value.Here is my code:
This code was from the MSDN site, but nothing seems to happen when I select rows within the GridView.
I got DataGrid Paging functionality on, I can see the paging 1,2,3,4,5.... but when i try to click on it to go to that page the datagrid just goes blank (does not render any record anything). My code is below:
I have a datagrid on my ASP.NET page and I would like to use arrow keys (Only up and down arrows) on my datagrid. Right now nothing happens when arrow keys are pressed. There are 3 columns. Only the last column is editable and 'tab' is available. I want only this column to be moved by arrow keys. Here is my code:
I am placing a dropdown list in the footer of a DataGrid like this:
In my code behind file, in the myDDL_OnLoad event handler, I call to the database, populate a SqlDataReader, and set the DDL's datasource to that datareader. I define what data columns should be used for the DataValueField and DataTextField of the dropdownlist. Then I call the DropDownList's DataBind() method. Everything works without error. But, when the dropdownlist is displayed, it has blank lines in it.
By that, I mean if 8 records are loaded into the dropdownlist, it will expand to a size appropriate for 8 rows but, it will be empty. there is no text in it.
Has anyone seen this type of behavior before? This dropdownlist is in the footer of a dynamically loaded ajax update panel so, it is difficult to see the source code to see what values are in the html element rendered to represent the dropdown.
I have a web application that takes information entered by the user and displays it in a few datagrids, that are located withing a multiview.
In order to enter a row to a datagrid the user enters some information and clicking on a button calls a function that adds the data to an arraylist, which is the source of the datagrid. In addition, every postback the data is binded to the datagrid.
It all works fine in the first time, but from the second row and on it enters only parts of the data and ignores the rest.
If I write the following code, teh gridview will no longer show the data
gridview.DataSource = null; gridview.Databound.
My question is , I want to make the same thing with a user control that contain a gridview. when I use the user control in an aspx page, I am able to populate it with data, but when I try to make this code, the Datasource does not show, instead, I see .DV. So I tried this code but then , I do not see DataSource property instead I see DV (DataView), when I put .DV = null, I get an error message that the object is not in existed. any idea how to clear the user control gridview from its data.

I have been using a datagrid on various pages. For some reason it stopped working. When pressing the Edit to make a change to the record, the page posts back two times and the record does not go into the edit mode. I am using IE 7 for my browser. Below is my code.
I have searched numerous articles for how to accomplish freezing the Header Row of a DataGrid or GridView component being to simply hide the header and then build table cells just above the component to define the columns. But the one that I'd like to get to work is by the use of CSS code. Problem is that this code seems to work for everyone else but it isn't working for me. Here's my Stylesheet code:
When I run my page I get all the styles applied but the header scrolls with all the other rows in the grid.
why this code is probably not working? I am using .NET Framework 3.5 and developing in VSS 2008 which may be why this doesn't work?
I have successfully downloaded sample code from Code Project which works using other techniques as well, but the code was written in .NET 1.1 Framework and VB.NET.
the client side validation is working for the adding date and time, but there is no validation firing for the count and room fields, I think i have coded them all the same, see sample for time and room below, maybe somebody see's something i missed? the validation group fires when the add button is clicked. also if possible I would like to get validation messages to appear in a validationsummary control that I already have coded and that is working when using the edit/update the rows presented with existing data.
How to do the datagrid cell editing? My need is "I want to update the datagrid cell values individually". At that time of editing, i want to pick the values from dropdownlist, calendar,etc.. controls.I tried a code, but its not working properly. I always taking the cell value only, not the control value.

I have a Hyperlink control in an ItemTemplate inside of a DetailsView. The DetailsView is inside a view of a MultiView which is inside of an update panel.
I am using binding syntax to bind the NavigateUrl property of the Hyperlink. However, the text shows up but when the mouse point moves over the hyperlink, the pointer doesn't change to a pointer hand like it should. And, nothing happens when the HyperLink is clicked. Here's the syntax I'm using:
I'm trying to set the ImageUrl property after I've uploaded an image so that I can display the newly uploaded image, but for some reason it's not working.
If I navigate from the record I've just updated and then return back to that same record, the image then displays. It just doesn't display right after I've updated it. Basically what I'm doing is this:
Sub FormView1_OnItemUpdated(Sender As Object, e As FormViewUpdatedEventArgs)
Dim MyImage As Image MyImage = FormView1.FindControl("Image1") MyImage.ImageUrl = "image1.jpg"[code]....
I've left out the path intentionally because I'm pretty certain that the path I'm giving is correct... again, if I navigate away from the record and then return to it, the image displays. In addition, when I view the "Page Source" to view the resulting html, the src property of the image tag is blank . So, it's not a path issue... the issue is that its not setting the src at all which is why the image is not displaying.
