I have a gridview each line has 4 linkbuttons - Edit , Update , Cancel , Delete and a few columns with data...For example TeamName and TeamEmail, and a hidden column that contains a validator (for ease of validating controls that are found on the same row , same naming container)
When Edit button is Clicked , the specific line goes into editing mode , Texboxes are created for TeamName and for TeamEmail .
I create dinamically (code behind ) a new textbox that reads the value from the TeamEmail textbox , i give it a new id (let's say "Email") , add that email to the controltovalidate property of my validator , and call the validate() method of the validator.
Everything works fine when i modify the value in a worng format , the validator err message appears , when i modify the TeamEmail value to a good email format , the validator property isvalid becomes true , and the update is running , but my textbox is empty :( updating the TeamEmail value to null.
This is some bad code but hope you understand what i meant :
This is my html coed of my gridview

This is the code that manages the validation:

I have a Gridview with edit and update feature enabled. It displays the data correctly but when I click on the Edit linkbutton(to edit the data), I get the error "Object reference not set to an instance of an object".
I tried debugging and found that the row which I click (say editindex is 1) loses its value. I could identify this while debugging the code, when the code flow moves to the rowdatabound event, the label (or for that matter any control in the rowdatabound event) shows a null value and eventually errors out.
I am unable to figure out as to why the control specified in the rowdatabound event loses its value when editing. Note: The lost valueow data is the one which I tried editing.
I am attaching the code which I have written for the rowdatabound event.

In my access datasource, I have set the selectcommand to what the user desires via a DDL. So the user chooses say, all names beginning with "B". But as soon as user clicks to page to the next page, the filter is gone. What is the way to preserve the filter. I have only merely rebound the gridview in the Pageindexchanging event which obviously is not doing the trick. Does this call for a session var to hold the users choice?

I have a GridView that has approximately 800 records. I have a search feature that finds a record and focuses to it. When I click Edit for that record, the Gridview flashes and goes back to the 1st row. If I search for the record again it is in edit mode. Is there some setting to keep focus where it is? I added the following code to try and keep focus, but it doesn't work.

I have a gridview with columns 'Edit', 'Delete', 'View Results' and other details. The 'Edit' column opens a modal popup to edit the record. The 'View Result' column is in a login view and this column is only visible to users belonging to the group 'Manager' as below:
[Code]....
When the page is first loaded, the hyperlinks are displayed correctly. however, after editing a record and saving the changes, the 'View Results' column loses the hyperlink.
I tried creating a temp hyperlink column outside a loginview control and this seems to work correctly.

I have a grid and on each row of grid i generate a radiobuttonlist with 2 items dynamically in rowdatabound. On the save button event i want to access the data of the row and save the data in DB with which ever radio button is selected.I tried different things but all in vain. I tried to use hidden field so that whenever any radio button is selected in a row then in javascript i will update the hidden field but user can select multiple rows so this is not a good solution.
Here is my code of dynamic radio button list generation in rowdatabound event.

I have a grid. I am building and populating it dynamically in C#. Below mentioned is my issue:
string s1 = "string1";
string s2 = "string2";
And then I have a header cell text which needs to be populated like this.
headercell.text = s1 + new string(' ', 20) + s2;
I am not able to get the extra 20 spaces between s1 and s2. It gives me just one space instead of 20 spaces.
I tried using headercell.text = s1 + s2.padleft(' ', 30); even then I am not able to get more than one space between strings s1 and s2.

I am stuck in chart controls...Here is my prob... There is a ListBox containing some items...when user selects multiple items from the list box I want to generate a dynamic table with the number of columns same as that of the number items selected in the listbox. And for each selected item I want to show a seperate chart in the columns...Currently I want the same chart control for every selected item (i.e. a static hard coded chart that i will replace later by dynamic values)....I am using a method that draws a chart control using a sample dataset... I am calling it each time when a new column is created..Also the DrawChart method executes for the first column only and throws an index out of range exception! after the first execution...my code is not working...here

I'm currently working on a project and I want to make as much things as possible performing on client side - with as little loading as possible. The project consist of three "main" pages. On one page I use jQuery DataTable plugin which is working great. One page has tabs (using jQuery). I want to put datacontrol (repeater) on this site and when user selects one item in dropdown, data in repeater loads on client side, without performing the action on server.

I have a table witch i programmatically fill with(multiple) IDs in the first column, options in the second and checkboxes in the third. The table is in a View as it is part of a wizard and is filled on view_Activate.
How can i get the checked property of the checkboxes when i pass to the next view? When i try to do that on view_Deactivate the table is already 0 rows...
I know i can use i checkboxlist(... whose properties i can get on view_Deactivate) but i'd rather use a table as it is easier to layout as i want it(header, columns, alignment,...).

When I am setting the width of a column in a GridView I use the HeaderStyle-Width:
<asp:BoundField DataField="AnalysisId" HeaderText="ID" SortExpression="AnalysisId" HeaderStyle-Width="25px" />
<asp:BoundField DataField="AnalysisId" HeaderText="ID" SortExpression="AnalysisId" HeaderStyle-Width="25px" >
<HeaderStyle Width="25px"></HeaderStyle>
</asp:BoundField>
Two questions. First, is HeaderStyle-Width a preferred/best way to manage column width in a grid view? And second, how do I suppress the genration of the the additional code?

Tried several different ways to do this but am just not seeing it. Proably a quick solution for someone more skilled than me.
I have a gridview generated from a datatable. One of the columns is "client name" whose data is generated from a class.
I added a link button for the column header that fires a sub that should sort the datagrid, but is not.
Here is the code I have so far that creates the gridview which works fine:
Private Sub PopulateCaseListGrid()
'Kill the existing DataSource, in case of a page reload
gvCaseList.DataSource = Nothing
'Create a datatable with whatever column you want to use

I am currently working on a module in which I am creating an auto generated column gridview, and I have set the Auto generate edit button field to true. What happens now when I click the edit button The primary key field is turned in to edit mode which I want to restrict from being updated.
To restrict the same I have hard coded a template field which holds that column, But as I have set the AutoGenerateColumns Property to true the gridview automatically creates a duplicate field for holding the primary key column. For which I want to delete that particular column.
My Designer Code is:-

in page load I am binding the grid view.
Even I have tried to hide that column doesn't make any difference for me.
