I have a gridview and when a user selects a row I want to change the view in my multiview and display several new gridviews.

View 1 RepliesI could really use some help on this. I have been searching for a solution on the web but haven't been able to find much help.I need to add textboxes to a gridview edit cell, based on the number of rows of text in one of the cells. I have coded the capture of the number of textboxes I need to add.
But I am not sure which Gridview event to add the code, when going into edit mode, to run the loop that will insert additional Textboxes in a specific column of the row selected to edit.
The user sees colA that has text with line vbCRLF's embedded say:
"This is sample text."
"Line2"
"Line3"
My code reads three Carriage Return, Line feeds. So when the user goes into Edit mode I want to provide one text box for each line or more accurately, add two more as one will already exist.
I have a list box that is bound to a table in a database. It produces a list of companies. The user will then come along and select multiple companies that they want to view information about, and then they hit a select button which I'll display the company information (e.g company name, company site, address e.t.c) in a gridview underneath. However the issue that I am having is that it only displays ONE of the multiple companies selected and its always the top one. How I get all the companies to be displayed in the gridview?

I have aspx gridview with checkbox on evryrow, what is required is whenever we check any of the rows, a query should be launched to change the specific agent -each row consist of agentID, Pass, Status- to Paid Status. using javascriptWhat I need to know is how to loop to get the Checked row and get the ID of the row checked so that I can get THe ID of the Agent in thos row so that I can update its status.using javascriptI found something similar on stackflow:t GridView selected row DataKey in JavascriptBut it is not my case, what is needed is at the check of a checkbox a javascript function should launch through which I could update the selected row in grid view after having the index of this row and this all to avoid refreshing the page.

I need to disable every control on my Form so that the user can not click or press any key that will change values of listboxes and other controls on the form. I need to be able to lock the whole Form like this because as part of the project I have to print the form 3times with 3 different colors and the only way I've been able to get it to work is with a timer. So for about 3 seconds the form is changing colors and printing itself, so in between that time the user could accidantely click something and change a value on the form when all three prints should be of the same form, only difference is in the color.I can't use disable as that will make all the controls look faded and messed up, I need a clean way to prevent anything from being changed.
