asp.net c# Change style for all rows inside a datalist on condition

Question

In a Datalist, onitembound I apply style to a div based on a condition with

protected void DataList2_ItemDataBound(object sender, DataListItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
    {
        DataRowView drv = (DataRowView)(e.Item.DataItem);
        int rating = int.Parse(drv.Row["A1"].ToString());

        if (rating > 0 && rating < 5)
        {
            TextBox txt = (TextBox)e.Item.FindControl("txtA1");

            txt.Attributes.Add("style", "background-color: Green;color:white;font-size:9px");

        }
    }
}

but in the Datalist I have 21 controls (txtA1 .... txtA20). Is there a way to apply style for all divs that meet the condition?

Sorry Jignesh, I mislead you. Each txt1, txt2...txt21 has a value, actually is a sum of the column but it's not important for my case. What I want to do is to color green the div that has a value less than 5. With DataRowView drv = (DataRowView)(e.Item.DataItem); int rating = int.Parse(drv.Row["U1"].ToString()); if (rating > 0) { TextBox txt = (TextBox)e.Item.FindControl("txt1"); txt.Attributes.Add("style", "background-color: Green;color:white;font-size:9px"); } I get the value for each div and apply style. I was hoping for a way to check all divs (txt1, txt2,...txt21), one by one and apply style for those meeting the criteria

Thank you Jignesh for your answer, what I need is to check the value for each txt1..21 box and if is between 0 and 5 to have a color. I tried your code buy having protected void DataList2_ItemDataBound(object sender, DataListItemEventArgs e) { if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) { for (int i = 1; i but I get the error " Input string was not in a correct format. "

Hello Marius, If your text box name starts with txt... then you can find the below, protected void DataList2_ItemDataBound(object sender, DataListItemEventArgs e) { if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) { DataRowView drv = (DataRowView)(e.Item.DataItem); int rating = int.Parse(drv.Row["A1"].ToString()); if (rating > 0 && rating
