This has been driving me crazy for a while! I have a table with each cell having an id such as cell1, cell2, cell3, etc.
I am trying to assign data to cells through a loop so i have something like this
[Code]....
The problem is that after asp.net assigns a ClientID to the cells I am no longer able to find them because they get names like ct100_gameContent_cell1. Does anyone know how I can solve this problem??
Object reference not set to an instance of an object. when I try to access these dynamically created controls using FindControl.
I have a dynamically created control within a table cell. The table itself is contained within a page that has a master page. I've tried so many different ways to access this control.
Below is the latest iteration
AttrTable is the asp table, and row.Attr_Type is the name I've given to the control (it iterates through a datatable to set the names for the control)
tmpVal = CType(AttrTable.FindControl("TD_" & row.Attr_Type).FindControl(row.Attr_Type), DropDownList).Text
Below are various ways I've tried to access the control:
Dim form As Control = Page.Master.FindControl("form1")
Dim content1 = form.FindControl("ContentPlaceHolder1")

i we click a table cell than color is blue and we again click a different cell the first color is remove and second is bule

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"

View 1 RepliesI 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've a GridView bound to an object data source which gets data from a remote server. The GridView is inside an AJAX UpdatePanel. For each GridView row, I have a status data item for a person's status(like busy, free, etc.) and I need to show a running timer since a person has been in the current status. Different persons can be in different status at different times and so running timer for each person needs to be different and should be reset when a person changes status. Is it possible to show such a running timer for a cell in each row of a GridView and manipulate it differently i.e. start, stop and reset each instance individually?

I have a <table> with two <td>. This <table> resides inside a GridView, so I FindControl like below. Now I need to do a calculation of height that if MessageBox1 have a height that is less than 306, then I need the MessageBox2 to have the remaining height.
For example if MessageBox1 has the height of 206, then MessageBox2 need to have the height of 100.
I think my problem is how to convert the height of MessageBox1 correctly and set the remaining height to MessageBox2 ?

I have a dynamic Gridview that I build on the fly. It works great. Now, I want to put paging on it. I have put the following code as an event on Pageindexchanging. When I do, the system tells me that the BindGridControl is not declared. The other lines have no error on them. What am I doing wrong? The name of the Datagrid is MyGridview. If I comment out the BindGridControl the system does not get an error but it of course does not show the second page when I click on it.
[Code]....
I did it with DIV tags rather than trying dynamic page building
I believe this is a newbie question, but i just figure out my head around.. does anyone know how to auto adjust the control in the table cell so its width follows the width of table cell?
