My JavaScript is referenced in my page this way:
<script src="JScript1.js" type="text/javascript"></script>
The following are the functions inside that script file:
function multiplication(txtQuantity) {
var weight = document.getElementById(txtQuantity).value;
}
function f(sender, args) {
args.IsValid = false;
var gridview = document.getElementById("<%=Gridview1.ClientID%>");
var txt = gridview.getElementsByTagName("textarea");
for (i = 0; i < txt.length; i++) {
if (txt[i].id.indexOf("TextBox1") != -1) {
if (txt[i].value == '') {
args.IsValid = false;
}
else {
args.IsValid = true;
}
}
}
}
function f1(sender, args) {
args.IsValid = false;
var gridview = document.getElementById("<%=Gridview1.ClientID%>");
var txt = gridview.getElementsByTagName("textarea");
for (i = 0; i < txt.length; i++) {
if (txt[i].id.indexOf("TextBox2") != -1) {
if (txt[i].value == '') {
args.IsValid = false;
}
else {
args.IsValid = true;
}
}
}
}
I want to call these functions from my code behind and assign them to a custom validator.
I have attempted the following but it's not working:
<asp:CustomValidator ID="custValCountry" runat="server" ValidationGroup="Country"
ValidateEmptyText="true" ControlToValidate="TextBox1" ClientValidationFunction="javascript:f"
ErrorMessage="Other is required"></asp:CustomValidator>
In my RowDataBound event, I have written the following which is also not functioning as expected:
protected void Gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
TextBox txt = (TextBox)e.Row.FindControl("TextBox1");
Page.ClientScript.RegisterClientScriptBlock(txt.GetType(), "onBlur", "multiplication('" + txt.ClientID + "')");
//Page.ClientScript.RegisterClientScriptBlock(, "Script", "alert('Records Successfuly Saved!');", true);
// txt.Attributes.Add("onBlur", "return javascript:multiplication('" + txt.ClientID + "');");
//TextBox txt1 = (TextBox)e.Row.FindControl("TextBox2");
txt1.Attributes.Add("onBlur", "return javascript:multiplication('" + txt1.ClientID + "');");
}
}
Any help would be appreciated.
