Forms Data Controls :: Datagrid Validation Controls Partially Working?
Feb 15, 2010
the page can be seen here [URL]
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.
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 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 a placeholder to which I programmatically add DataGrids... In the DataGrids, I programmatically add TextBoxes along with dynamic validations. Somehow, the DataGrids show up, but the dynamic validations don't work. If I set them to static, the blank space for them appears, but still, they wont work.
i am using datadrid and i want to display it in vertically but it is continiously showing in horizontally style. i have made changes in view , property but still not working.
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:
[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.
How to do the datagrid cell editing? My need is "I want to update the datagrid cell values individually".

I'm trying to write my first server control. It's supposed to be a pager (like in the GridView Control Pageing-"thingy").
(It looks something like this : 1 2 3 4 5 6 7 8 9 10 ...)
I'm trying to implement it by making the control inherit Table properties and then adding two rows. One row has a hidden field that has the current selected page and the other has LinkButtons in individual TableCells.
The problem I'm facing is that the LinkButton.Click event only fires on the first 10 linkButtons but not the dots (...). What I mean is, when I press the dots (...) it renders like this: .... 11 12 13 14 15 16 17 18 19 20 ... BUT when I press any of these LinkButtons the control just "reloads" itself and renders from 1 to 10 ... (and the Event never fires) I don't know what I'm doing wrong but I think it has something to do with the "override" functions because I don't know which to use. I have tried quite a few but haven't found the right way to do this. The Code I got so far:

This is DataGrid control, and the first column. Everything works fine except ItemStyle-HorizontalAlign is not working :(The HeaderStyle-HorizontalAlign is working fine. But ItemStyle doesn't work, it only aligns to the far left.I want to align this to the center.

I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.
I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.

I'm trying to create a web page using Visual C#.NET 2010 on a 3.5 framework that allows users to select items through a series of dropboxes which are then saved to a temporary display grid. The problem I'm having is that I wish to allow users to save multiple combinations of selections which are saved to various rows of the display table.
Below is a sample of what I'm trying to do.
C#
[Code]....
And here is the ASPX page:

The problem I'm having is whenever I try to edit the selected column all other columns are cleared. I need to have them remain while only the selected row is altered.
Here is the situation:I have a Datagrid which is going to display a number of rows. I want to click a button on the datagrid and have the following occur
open a row underneath the row clicked, without hiding or replacing that row Open this row so that it spans all of the columns as one continuous row where i can put form fields and/or just data formatted as I would like and not just in columns.Be able to close that new row. While I do most of my work in VB.NET, don't think that is a requirement for answering this.I have managed to currently take the first column (with the "Edit" button) and when clicked to Hide the rest of the cells in that row Expand the button column to run all the way across the table Unfortunately I loose the clicked row's data, and I've only started getting this to work so I haven't tried too much, or getting data to bind to fields "on the fly"
