ex:-->
i ve two column ...A and B ON RAD GRID

AFTER CLICKING THE ADD NEW RECORD
IF I CLICK THE INSERT BUTTON WITHOUT ENTERING ANY VALUES ON BOTH THE COLUMNS
I NEED TO SHOW AN ALERT

Hello Shankar,

One suggestion would be adding RequireFieldValidators for the TextBoxes from code behind. You can wire the ItemCreated event of the grid to add a validator in the handler. The following documentation describes how you can achieve this.

yeah shinu its working but
my scenario is different


col_1    col_2    col_3    col_4    col_5

if i leave all the 5 columns blank ,alert should come
if am entering  in any one of the column also is acceptable so no alert is needed

Hello Shankar,

Here is another approach that I tried for showing an alert when any of the textboxes is empty (while inserting).

CS:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)

{

if (e.Item is GridEditFormInsertItem && e.Item.OwnerTableView.IsItemInserted)

{

GridEditFormInsertItem insertedItem = (GridEditFormInsertItem)e.Item;

TextBox column1 = (TextBox)insertedItem["col_1"].Controls[0];

TextBox column2 = (TextBox)insertedItem["col_2"].Controls[0];

TextBox column3 = (TextBox)insertedItem["col_3"].Controls[0];

TextBox column4 = (TextBox)insertedItem["col_4"].Controls[0];

TextBox column5 = (TextBox)insertedItem["col_5"].Controls[0];

LinkButton insert = e.Item.FindControl("PerformInsertButton") as LinkButton;

insert.Attributes.Add("onclick", "return ShowErrorMessage('" + column1.ClientID+"','"+column2.ClientID+ "','"+column3.ClientID+ "','"+column4.ClientID+ "','"+column5.ClientID+"');");

}

}

JAVA SCRIPT:

<script type="text/javascript">

function ShowErrorMessage(col1, col2, col3, col4, col5) {

var column1 = document.getElementById(col1);

var column2 = document.getElementById(col2);

var column3 = document.getElementById(col3);

var column4 = document.getElementById(col4);

var column5 = document.getElementById(col5);

if ((column1.value == "") && (column2.value == "") && (column3.value == "") && (column4.value == "") && (column5.value == "")) {

alert("fill atleast one field");

return false;

}

}

</script>

Shinu.
