How to set the value of a checkbox in a datagrid?

[KidHoss]

I get the current state of a checkbox item in a templatecolumn in a datagrid by creating a checkbox item and do findcontrol (dgItem.FindControl("chkExportItemSelected"))

After reading stored data from a database I want to loop through the datagrid and set the checkboxes as related to the data from the database.

My question is how do I set the checked state of the checkbox as I loop through the datagrid?

Use the Itemdatabound Event of the grid. Then get a reference to the checkbox like you have done already. then you can set the checkbox1.checked = TRUE.
If you are not doing this on a post back you can loop through the grid like this:
Dim dgi As DataGridItem
For Each dgi In datagrid1.Items

Next

I am not reacting to the databinding of data to this datagrid. I am reacting to a button being pressed that causes a set of data to be retrieved from a database. I loop through the dataset from the database read and as I find a match in the datagrid, I want to set the checked value of the corresponding checkbox to true. How do I reference the datagrid checkbox to set it's value, not test it's value?

Thanks,

Then Use the second method I posted above in the button click event.

That is how I loop through the datagrid items.... but how do I set the checkedd state of the embedded checkbox? I know how to check to see if teh checjk box is check or not. I know it will not be checked. I want to check it based on data read from rthe database. Pwerhaps I am not understanding what you are telling me, but your reference does not mention setting the checked state of teh checkbox. Every time I try to set it to checked, it tells me the property is read only and I cannot change it.

Dim dgi As DataGridItem

For Each dgi In datagrid1.Items
dim cb as new CheckBox
cb = findcontrol (dgItem.FindControl("chkExportItemSelected"))
cb.Checked = TRUE

Thank you very much. Obviously I did not understand what you were trying to tell me. I thought I was creating a new control and did not connect that I was creating a way to reference the existing control.

Again, Thank you very much.
