.net - Devexpress Grid - PerformCallback Generates Invalid Viewstate?
Dec 13, 2010I have a DevExpress grid that needs to be refreshed every time the value in a combobox is changed. For example, I have a combobox that sets the grid's page size. One of the requirements is that the combobox does not cause a full postback.
The combobox is declared like this:
<asp:DropDownList ID="cboPages" AutoPostBack="false" runat="server"
EnableViewState="false" OnSelectedIndexChanged="cboPages_SelectedIndexChanged" />
On selected index changed, it sets a cookie whose value is the selected value. When the combobox value changes, a javascript function is called:
function PerformCallbackOnGrid(grid) {
try {
grid.PerformCallback("refresh");[code]....
The function is attached in code behind: this.cboPages.Attributes["onChange"] = "PerformCallbackOnGrid(" + this.GridClientID + ")";
After performing these steps:The user changes the grid page size using the combobox, so PerformCallback is called at least once.
The user presses F5(refresh).
The user tries to change the page size again.
an 'Invalid viewstate' error message appears.
I have tried setting ViewStateMode to Disabled for the grid, also EnableViewState="false".

C# - Access Object From Javascript DevExpress?
Aug 24, 2010I wonder why I cant access Object by ClientInstanceName from javascript.
example:
function NextStep(pageControl) {
currentStep = pageControl.GetActiveTabIndex();
switch (currentStep) {
case 0:
selectedRowsCount = GridViewClient.GetSelectedRowCount();
break;
}
The error is:
There is no definition for GridViewClient;
but ClientInstanceName is set to GridViewClient
Case is that I have thos grid on other tabs in ASPxPageControl so that these aren't visible but What I want to do is to refresh one of it before displaying it and I wanted to use client side ASPxGridViewClient.Refresh().
DevExpress AspxGridView Filter In ObjectDataSource
Mar 16, 2010One Page In the Page, a custom control In the custom Control, a AspxDropDown The AspxDropDown, has a DropDownWindowTemplate In the DropDownItemTemplate, I add a GridView and a paging/sorting/filtering enabled ObjectDataSource When handling the Selecting event of the ObjectDataSource, I should set filter parameters for the datasource. There filter parameters should come from the FilterRow of the AspxGridView (preferably using the AspxGriedView.FilterExpression property). The problem: the AspxGriedView.FilterExpression property is not set to the proper values (set by the user). Did anyone find a good implementation of what I'm trying to do here?

Preserve Paging With The DevExpress MVCxGridView Control?
Jan 12, 2011I'm working with the 10.2 version of the DevExpress MVC controls. I have a page hosting a MVCxGridView and I need to preserve the current page when navigating away and back to this particular page.
I can see from the old ASPxGridView documentation that there's a PageIndex property, but this seems to only be accessible from a WebForms/Code Behind/Server Control type context. I'm using MVC and can't figure out how to preserve this page setting.
I've tried the cookie settings with the control but those don't seem to persist for me.
