Web Forms :: How To Retrieve The Table Cell Height In C#
Mar 19, 2011
I had a problem for a long time but now wonder how I will solve this. Perheps it is easy.
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 ?
How to set Height and ItemSource(Business Object as DataSource for Cell) for every Cell in DataGrid/ Grid? Shown below is part of code I am currently using with Grid Control. What I am currently doing is that I am using ListBoxItem, set Item Height and ItemSource at ListBoxItem Level, Add ListBoxitem to ListBox and then Add ListBox to Grid, It leaves me with just one row and multiple columns in the Grid, which is perhaps not the best way of doing it as it doesn't allow me to take benefits from UI Virtualization of Grid.

I am open to use any control i.e. Grid/ DataGrid provided it allows me to set Cell Height and item source at Cell level. In my requirement, Cell height depends on the Item duration and size of image, which means the height of the cells may not be same across cells in any particular row.
I am retrieving an image from SQL Server to display on a new page in my ASP.NET 4.0 application using this method (one of my posts):
How to display an image based on SelectedValue in a GridView?
I am then displaying the image in a new window using this method: (one of my posts):
How to display an image in a new window
What I am trying to do is get the height and width of the image so that the new window is created with the same height and width as the stored image. I guess there are two ways of doing this:
Create a height and width column in my database and store the values when the image is inserted into the database Retrieve the image from the database and calculate somehow the height and width just before displaying it and then resize the browser window to the right size.
I already have over 150 images in the database so that makes option 1 difficult because I would have to go back over my db and calculate height and width for images that are already in the db. Therefore I would prefer to use option 2, or maybe there's another option? How would I go about doing this?
I am using VB and trying to get the first value of the cell of a gridview. The gridview is returning a header and 1 value.
In the code behind I have used the below, but the textbox is showing " ". It is not populating the first cell of the gridview databind.
Protected Sub GridView3_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs)If (Not (e.Row.DataItem) Is Nothing) Then ' Set the capacity label text TextBoxTest.Text = e.Row.Cells(1).Text End If End Sub
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;
I have a datagrid whose columns are autogenerated (based on the results from an SQL SELECT query). However, I need to retrieve values from certain cells across the datagrid, using the following code to step through the results.

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??
I have a child table inside the cell of parent table. I want to stretch the child table so that i covers full space in the cell of parent table. Also i need to keep the DOCTYPE tag. how to achieve this.
I've tried doing this, but it seems to just be ignored. I found a few articles saying that if you wanted to do this then you had to make sure that the parent object was also 100%. I have the following:
