Value of a template column cell

[TerryDad2]

I am trying to obtain the value in the datagrid from a template column.

e.Item.Cells(5).text returns a null value on template columns, but obtains the displayed text on a databoundcolumn.

What is the correct syntax for obtaining the displayed value in a template column?

Terry - you need to cast the contained control and obtain the value from that.

It will probably be something like

dim lblTheLabel as label = ctype(e.item.cells(5).controls(1), label)
and then your value is lblTheLabel.text

it's controls(1) because usually controls(0) is a literal control or something

Using that I get a
ArgumentOutOfRangeException: Specified argument was out of the range of valid values. Parameter name: index
error.

This makes me think I am pulling from the wrong column, so I have moved to trying to get the value from cell 0 which I know is a template column. (dim lblTheLabel as label = ctype(e.item.cells(0).controls(1), label) and still get the same problem.

What are the controls that are in a tablecell?

Mark's post got me looking at what the control really is and I figured it out. The syntax is

CType(e.item.cells(5).controls(0), DataBoundLiteralControl).text

Try controls(0)

Also, you can put a breakpoint in (if you're using VS) and query the code in the command window until you get it right.

for example, when you're at the breakpoint, type this in the command window

? e.item.cells(0).controls(1)

it will output a whole load of stuff but by browsing it and changing the index for the cells and the controls, you will be able to eventually find the one you want.

If you are still having problems, post the HTML behind your datagrid

Yeah terry - I assumed that you'd accepted the default for a template column, which is a label in the item template and a textbox in the edit item template.
Glad you worked it out.
