Alternatively you can display a javascript alert after a postback by
Page.ClientScript.RegisterStartupScript(this.GetType(), "testkey", " window.alert('Your Alert Message')");
|

I use ASP.NET + C#
In My form I have a Gridview inside gridview i use a dropdown list
In dropdownlist it contain --Select-- and other items
I want to add a validation to this dropdownlist so that the user must choose an item other than --Select--
I need to validate using javascript .How can i do that
|
|
|
|
|
//if u have given selectedindex for your dropdownlist --select-- as 0
function error()
{
if ( document.getElementById('..._dropdownlist').selectedIndex = "0")
alert('select atleast one');
}
//but it will more easy if u provide a required field validator.

i will not work bcs i place the dropdownlist inside the gridview .
|
|
|
|
|
Add a javascript function through attributes.add in cs
for(int i=0;i< gridview.rows.count;i++)
{
DropDownList ddl = (DropDownList)gridview.rows[i].cells[cellid].findcontrol('id');
ddl.attributes.add("onchange","return func("+ddl.clientid+");");
}
Send the row id from the cs file
function func(ddl)
{
//Do the validation in javascript
}
Hope that helps!!

Hi, I have a grid, which has an ItemTemplate and an EditItemTemplate, my concern is how do I get the controls in the EditItemTemplate, my grid columns looked like this...
<asp:TemplateField HeaderText="Price Type" HeaderStyle-CssClass="first" SortExpression="PriceType"><br />
<ItemTemplate><br />
<asp:Label ID="lbl_pricingtype" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "PriceType[0].PriceTypeDesc[0].Description")%>'<br />
ToolTip='<%# DataBinder.Eval(Container.DataItem, "PriceType[0].PriceType")%>'></asp:Label><br />
</ItemTemplate><br />
<EditItemTemplate><br />
<asp:DropDownList ID="ddl_pricingtype" runat="server" CssClass="first" Width="90px" onchange="ddl_pricingtype_change(this.value)"><br />
<asp:ListItem Text="Please Select" Value="-1"></asp:ListItem><br />
<asp:ListItem Text="0 - Price1" Value="0"></asp:ListItem><br />
<asp:ListItem Text="1 - Price2" Value="1"></asp:ListItem><br />
<asp:ListItem Text="2 - Price3" Value="2"></asp:ListItem><br />
</asp:DropDownList><br />
</EditItemTemplate><br />
<HeaderStyle CssClass="first" /><br />
<ItemStyle CssClass="first" /><br />
</asp:TemplateField>
Now I can get the value from the ItemTemplate label using OnRowEditing event but I can't seem to find the Dropdownlist control to set the selecteditem.

there is a sample program in which using EditItemTemplates are given..
