I'm used to Dreamweaver where this is possible. I find it hard to believe that I would need to use a 1 column gridView control.
Is there a way to drag one field from the db Explorer window onto my page and NOT get a grid view?
Or alternatively, I used to be able to put something like this in ASP classic (years ago!) <%= Eval("User") %>
I'm reading an invoice dataset and building a html table with checkboxes and textboxes in it, and I put that code in a postback = false block, then i got a button and a literal. The button click will loop through the html table checkboxes to calculate a total and assign it to the literal and display it. I got everything working except one thing, every time i click the button, the html table refreshes and lost all the value in textboxes....even though I put the html building block in the postback = false block,it seems like it still won't preserve the values in the textboxes once there's a button click...Anybody knows a solution to that? I want the textboxes keep what values are there.
Here is the code part:

I need to do a drag n drop for table cell. I need every feature of Ajax ReorderList such as when item 2 is drag to position no 3, item no 3 will be automatically goto position 2. However i need every item in Ajax ReorderList .
I have try many ways in trying it such as using customized tool: Telerik (RAdGrid,Scheduler), DevExpress , ComponentGo! and also PilotScheduler but all does not fullfill the business requirement. May be the requirement for solution is too rigid. Below is my table design
Date1 | Date 2
Shift1 | Shift2 | Shift3 |Shift1 | Shift2 | Shift3
Mch 1 Product1 Product3
Product2
Mch 2 Product4
Mch 3 Product5
User must be able to rearrange the item for example, user can drad Product 5 to Mch1 on date 1.
Does anyone has idea on this by binding ajax ReorderList to Table ??
I have a web page with various controls. Two of them are dropdownlists. The first dropdownlist gets populated from an xml file on the page_load event. This works fine. To the first dropdownlist a cascadingdropdownlist extender is attached which calls a webservice each time the selection in the first dropdownlist is changed. This works fine too. Underneath my two dropdownlists I have a button which posts the page back. However, when I have made a selection in the second dropdownlist and click the button I get the following error:

I have two possible header rows for a DataTable that I build dynamically. Setting the value of a cell works fine. Adding the cell to a TableRow works fine. The problem comes in where I have to build a second possible header row that uses the same cell.
An example is below.
trHead1 = New TableRow
trHead2 = New TableRow
tcCalc = New TableCell
tcCalc.Text = "Rates"
trHead1.Cells.Add(tcCalc)
trHead2.Cells.Add(tcCalc)
As soon as I make the second row add the cell, the cell disappears from the first row. This really doesn't make sense to me but that seems to be the way it is. If there is a work around other than duplicating the lines;
tcCalc = New TableCell
tcCalc.Text = "Rates"
I'm hardly an expert in css, so this is a bit frustrating. I have a grid that was filled with a repeater. I want each row to have a 1px border along the bottom to visually separate the rows.
#repeaterTable
{
border-left: 1px solid #A3A3A3;
border-right: 1px solid #A3A3A3;
border-collapse: collapse;

[Code]....
After it is done, I can't click on my calendar control. I was hoping to add somethign that would force a refresh in the script, but nothing I do works.
OK, here's my scenario. I inherited a website and I'm dealing with a quirk. I have a page that has a repeater with auto postback controls in it. And also a hyperlink or a button to open a RadWindow to add a new item or edit an existing one, the repeater probably could have been a Gridview, but forget that for now.
If you use the button to add a new entry or the hyperlink to edit, it works fine and closes and refreshs the page. BUT, after you click ANY of the auto postback check boxes and THEN try and use the new button or edit hyperlinks the RadWindow works, but on clicking SAVE or CLOSE it throws a dialog box in IE and Firefox letting the user know that:
"To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier."
IE's message is similar. Clicking RESEND works fine and everything is ok, but its a bit distracting to the user. The RadWindow open a page that has THIS javascript in it:
function RefreshParentPage() {
I have a UpdateProgress that trigger fine when I click on stuff inside my UpdatePanel. However I have some regular HTML link ("<a href>") outside of the panel. How can I reuse the UpdateProgress so when I click on those link, it will show my loading screen?

View 18 RepliesI just cant seem to view the HTML markup from a SQL Cell in a GridView.
When I set the AutoGenerateColumns=False it's easy because I can set the boundfield property in the DataGird ASP.Net markup. However, I can't seem to do anything with the gridview if the AutoGenerate is turned on.
Here is my vb code:
Code:
Dim sqlcmd As String = "Select [Bugs:], [QC#:] FROM " & """" & datasource & """" & Extra
Using con As New System.Data.SqlClient.SqlConnection(connexstring)
con.Open()
Dim da = New SqlDataAdapter(sqlcmd, con)
Dim ds = New DataSet()

I'm trying to dynamically generate a report in a table where the borders are different on each side of a cell or row, but can't figure out how. The TableRow, TableCell, and Table objects each have a BorderStyle property, but it seems to apply to the entire border rather than just one side. Can this be done without nesting tables?
For my case, I'd like a solid border around the first two rows of a table (because the first row has a cell spanning two rows), and a solid border around each subsequent row.
I'm creating an ASP.NET web application using C# and I want to know how I could assign an integer variable to the cell of a table. I could easily do it using a text-box and label but I'd like to use a table if possible.
