I am using telerik in buit filter functionality with only below code in HTML, but filter is not working when apply new search.
Kindly check attached grid for question explanation.
to limit filter creteria, below the JS,
var
column = null;
function MenuShowing(sender, args) {
if (column == null)
return;
var menu = sender;
var items = menu.get_items();
if (column.get_dataType() == "System.String") {
var i = 0;
while (i < items.get_count()) {
if (!(items.getItem(i).get_value() in { 'NoFilter': '', 'Contains': '', 'DoesNotContain': '', 'StartsWith': '', 'EndsWith': '', 'NotEqualTo': '', 'EqualTo': '' })) {
var item = items.getItem(i);
if (item != null)
item.set_visible(
false);
}
else {
var item = items.getItem(i);
if (item != null)
item.set_visible(
true);
}
i++;
}
}
if (column.get_dataType() == "System.Int64") {
var j = 0;
while (j < items.get_count()) {
if (!(items.getItem(j).get_value() in { 'NoFilter': '', 'GreaterThan': '', 'LessThan': '', 'NotEqualTo': '', 'EqualTo': '', 'Contains': '', 'DoesNotContain': '', 'StartsWith': '', 'EndsWith': '' })) {
var item = items.getItem(j);
if (item != null)
item.set_visible(
false);
}
else {
var item = items.getItem(j);
if (item != null)
item.set_visible(
true);
}
j++;
}
}
if (column.get_dataType() == "System.Boolean") {
var j = 0;
while (j < items.get_count()) {
if (!(items.getItem(j).get_value() in { 'NoFilter': '', 'EqualTo': '' })) {
var item = items.getItem(j);
if (item != null)
item.set_visible(
false);
}
else {
var item = items.getItem(j);
if (item != null)
item.set_visible(
true);
}
j++;
}
}
column =
null;
}
function filterMenuShowing(sender, eventArgs) {
column = eventArgs.get_column();
}
And the Grid is below,
<telerik:RadGrid runat="server" Width="580px" Height="350px" Style="margin: 7px 0px 0px 7px;"
ID="grdDelegation" AutoGenerateColumns="False" AllowPaging="True" GridLines="None"
PageSize="5" AllowFilteringByColumn="true"
<
ClientSettings EnablePostBackOnRowClick="true" AllowColumnsReorder="True" ReorderColumnsOnClient="True">
<Selecting AllowRowSelect="True" />
<ClientEvents OnFilterMenuShowing="filterMenuShowing" />
</ClientSettings>
<GroupingSettings CaseSensitive="false" />
<FilterMenu OnClientShown="MenuShowing" />
<HeaderStyle Font-Bold="true" HorizontalAlign="Center" />
