while using gridview whenever I go to edit an item it increases the row size - but this is because I have a multiline textbox as one of the edititemtemplates. It also increases the size of every row to the same size as the one that is being edited. Is there any way to keep the rest of the rows the same initial height and have an increased size just for the row being edited?

View 4 RepliesI am developing in .Net 4. I got a button to export grid view's data to excel, but one problem I faced is that the excel's rows height is very very 'short', I have to double click the row to expand it?I am not sure how can I set the height's property? I don see there is an option to do this.I got another version in .Net 3.5, same code though, but works perfect.
View 1 RepliesI have a 2008 c# application that displays data in a gridview. Two of the columns can contain text up to 500 characters. I have been able to handle these in the gridview by displaying the long text in a scrolling div tag. That works fine in the gridview, but when I export the gridview to excel, the row-height autofits to the large text fields, giving extremely tall rows. Any idea on how I can control the formatting to limit the row-height for the output excel spreadsheet? The approach I use for the export is described in

I was hoping this is simple but i have problems.
Basically i was only able to set the string color with itemstyle-Forecolor.
But how do i set the background of a column and also set height,width.Ok height may not work because i have an itemtemplate with predefined height.
Can this be done in a simple boundfield or must i have all my datafields in itemtemplates?
What i do for one column:

I created a grid and successfully done update, delete, filled functionality.
But whenever I m clicking on Gridview row, its hieght get increased and color of the row become red while clicking on edit button. But this problem is occuring in Mozilla,IE7 not in IE6. Project is running good in IE6. What could be the solution for this.
I exported some data from a gridview to an Excel with Images.
I need to give a specified height and width for all the rows and text to be aligned centre.
I have a gridview with results from a database query and columns where I add linkbuttons to individual cells.
something like:
Dim LB2 As New LinkButton
LB2.Text = "title"
LB2.CommandArgument = "argument"
AddHandler LB2.Click, AddressOf LaunchDocument
GridView1.Rows(i).Cells(10).Controls.Add(LB2)
There is a lot time involved in determining what cells get the linkbutton and I want to avoid going through that process on a postback when a user clicks one of the linkbuttons.How can I maintain these controls in the gridview after a user clicks a linkbutton and a postback is done?Right now the application has to go through the process all over again.
I have a scroll bar in GridView. I m maintaining scroll bar position with javascript. It is working fine.
I have one more datagrid in the same page. I want to apply same Javascript to that datagrid also. Here is the javascript I used.
<script language="javascript" type="text/javascript">
var scrollTop;
Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(BeginRequestHandler);
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
function BeginRequestHandler(sender, args)
{
var m = document.getElementById('divexample2');
scrollTop=m.scrollTop;
}
function EndRequestHandler(sender, args)
{
var m = document.getElementById('divexample2');
m.scrollTop = scrollTop;
}
</script>

How can I avoid this happening, and have fixed height colimns.
I have a HyperLink inside a panel.
I wonder if the the HyperLinks height can follow along ´automatically´ as the Panels height is changing as the HyperLinks is nested inside the Panel.
Is there a function for this?

I m doing paging in gridview. The paging one which acts like footer is of more height. I m trying to decrease the height but it is not working. when I m trying to increase it working.
View 3 RepliesI got an update panel, inside it, there is a grid view, and the data on grid views appear based on certain condition, so the number of rows will vary.
I got the following code, which when the grid view's row count exceeded 50, it will set the panel's height to 700px and with a vertical scroll bar. If it is lesser than 50 rows, it should reset the height.
On line 1, I actually wanted to reset the height, but somehow, it will set the panels height to 0. I tried alot of other values as well, and I dont think this line is helping.
The reason I want to reset the height is that I wanted the panel to expand according to grid view's row. And the reason I set to 700px is because i wanted to control the page viewability.

It's basically how to create an editable gridview.
I've got it up and working, but I need to change the width/height of the textboxes when the gridview is in edit mode.
The problem is, when the textboxes are rendered, they don't have ID's so I can't use FindControl to modify the textboxes.
Adding textboxes in the template items just created an independant - textbox that doesn't do anything.
My question is, how can I find these textboxes & change their height/widths, or how can I find these textboxes & assign ID's to them...so I can modify their height/widths?
Here's a snippet of what I've been playing with....haven't had any luck though...I'm probably way off:

I am adding linkbutton dynamically (actually above snippet tells what I am actually doing, in reality TableRow and TableCell are added dynamiccally). My problem is, I am not setting height of linkbuttuon which will added dynamically. I have no idea what text I have to add to linkbutton.
What I want, after all the link buttons are added, iterate through each added lin button, get the height of each linkbutton, store the max height, then re-iterate throgh the link buttons and set the height of each link button to max height.
