Why would you try both of those? Don't you know what you put in the cells? :confused:

Dear Mike maby i miss-explained what i want to do, i have a table which contain a checkBox on the first cell of each TableRow, so foreach tableRow i'm checking if the the first cell is checked i read the value of the second cell so i can use it to delete A certain row from my database, so i must read the value. please if you have an answer of my question, help me thank you for your concern

What value? You still have not posted what you put in the Cell that you want to read? Don't you know?

the table is already populated its full of values i want to retreive that value. here's the code:

foreach(TableRow tr in TbTariffTb.Rows)
{
TableCell cell = tr.Cells[0];
TableCell celCli=tr.Cells[1];

foreach (Control control in cell.Controls )
{

CheckBox checkBox = control as CheckBox;
if (checkBox != null)
{
if (checkBox.Checked)
{
//retreive the value of tr.Cells[1]
}
}
}

}

Populated how? Dude, you have now posted THREE times and you still have NOT SPECIFIED what you are putting in those cells that you want to read from. Without that information we can't help you. I'm done with you now, good luck.

your on a good way but there is a slight detail. Your Code:

foreach(TableRow tr in TbTariffTb.Rows){TableCell cell = tr.Cells[0];TableCell celCli=tr.Cells[1];foreach (Control control in cell.Controls ){						CheckBox checkBox = control as CheckBox;if (checkBox != null){ if (checkBox.Checked)  {    //retreive the value of tr.Cells[1]	
}}}}

My Advice

foreach(TableRow tr in TbTariffTb.Rows)
{
	CheckBox checkBox = tr.FindControl("IDofYourCheckBox");
	if (checkBox.Checked)
	{
		// Option 1: scan all Cells
		foreach (TableCell cell in tr.Cells)
		{	
			String value = cell.Text;	
		}

		//Option 2: scan the wanted cell
		String Value = tr.Cells[1].Text; // if not in edit mode
		String Value2 = ((TextBox)tr.Cells[1].Controls[0]).Text; // if in Edit mode

	}
}

ou might even have to cast: CheckBox checkBox = (CheckBox)tr.FindControl("IDofYourCheckBox");

thank you a lot digimanus, i really apreciate your answer a lot thank you

[michael_jhons]

digimanus i tried all methods u gave me, which i alresdy tried it before String Value2 = ((TextBox)tr.Cells[1].Controls[0]).Text; an error occured it gives me: specified cast is not valid, do you think textbox is the control which has to be specified for this cell ? thank you for your help

IS the row in Edit mode? (EditIndex > -1 in GridView) Than use the above code Else String Value2 = tr.Cells[1].Text; Otherwise. Set a breakpoint on the line with the (TextBox) cast. When reaching the breakpoint (Build = debug) add a watch on tr.Cells[1].Controls See how many controls the Count gives. If larger than 1 try in the watch all other controls in the array like tr.Cells[1].Controls[1] tr.Cells[1].Controls[2] tr.Cells[1].Controls[and so on] In that case you can see in which control your data exists. Have Fun

it's alright i was populationg the cell by this method: tablecell.Controls.Add(new LiteralControl(SomeString)); when i used tablecell.Text=SomeString; it's working fine Thanks for the help
