View 2 Repliestry to have custom controls in a DevExpress grids detail row. When ever a row is expanded I would like to load data into those custom controls based on the Masters Key.I am using the detailrow expended method.
protected void grid_DetailRowExpandedChanged(object sender, ASPxGridViewDetailRowEventArgs e)
if (e.Expanded)
{
int id = Convert.ToInt32(grd.GetRowValues(e.VisibleIndex, "ID"));
...
}
The problem is I don't know how to access the custom controls in the expended detail row. I don't see any Row or Items properties on the grid, which would have been with a FindControl().
I added DevExpress GridVIew into my ASP .NET WebForms app. GridView works fine but it generates a huge hidden input with base64-encoded postback data and loads several large javascript files. I don't need any client-side functionality. So, how to disable client-side functionality of this control?

How can I do this and in which event would I do this in?

View 2 RepliesI currently use the ASPxGridView from DevExpress (2010 v1). Has anyone had any success creating double headers where the first set of headers span across multiple subheaders?
HeaderSpanColumn1

There doesn't seem to be much verbage about this on their support site since it isn't officially supported.

View 2 RepliesI have a ASPxGridView with DetailRow in this row there are three additional ASPxGridViews. Each detail ASPxGridView contains EmptyDataRow templates with link to create a new row:
<a href="javascript:gridViewDetails1.AddNewRow();">AddNewRecord</a>
When master ASPxGridView rows is 1 or 2 then new rows in detail grids adding fine, but if in master ASPxGridView rows about 10 or more then when I clicking on detail grids link to add new row the loading panel appers for unlimited time and FireBug->Net shows that status of POST is timeout and time is about 1 sec.
How can I repair it?
To AGoodDisplayName:
are the detail row gridviews bound to anything?
yes of course, inside the details row of master gridView there are 3 another gridView and each of them have a separate ObjectDataSource.
Are you expanding more than row at a time?No, I have only one row at time:
AllowOnlyOneMasterRowExpanded="true"
Yep:<asp:ObjectDataSource ID="dsMaster" runat="server" TypeName="..." SelectMethod="...">
</asp:ObjectDataSource>
<dxwgv:ASPxGridView ID="gridViewMaster" ClientInstanceName="gridViewMaster" runat="server" DataSourceID="dsMaster">[code].....

One 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?
View 1 RepliesI want to change AspxGridView mode on server side. For example :

I'm trying to Find a control in my edit form just before I hit the submit button on it(custom), however it isnt returning any value entered in the memo, even though I have inputted some value. It seems like its resetting. Its not binding to anything.
Code:
Dim Memo As ASPxMemo = CType(ASPxGridView_BranchQueue.FindEditFormTemplateControl("ASPxMemo_ResubmissionRationale"), ASPxMemo)
MsgBox(Memo.Text.ToString())
I've implemented a custom sort for a aspxgridview, following the steps mentioned here: [URL]
However, I've noticed that it only sorts the current active page, so whenever I go to another page I have to click again on the column to sort it.
Is this behavior correct, or am I missing something? How can I solve it?
PS: I thought about capturing the PageIndexChanged event and manually sort the active page, but that seems too hackish...
I have a ASPxGridView. In it(for the uninformed) is only a DataSource property for telling it what data to load. My problem is that I'm simply trying to mock up an example and don't need to tie it to an actual database. How would I do this? I basically just want a few rows and some columns but since it only takes a datasource I'm not sure how to do it. Would ObjectDataSource be what I'm looking for?

Im implementing custrom delete by adding to my ASPxGridView GridViewColumnCustomButton.
Then on my GridView I handle ClientSideEvent
<ClientSideEvents CustomButtonClick="function(s, e) { customButton_OnClick(s, e); }" />
JS:function customButton_OnClick(s, e) {
if (e.buttonID == "customButtonId") {
e.processOnServer = confirm("Really want to delete?");[code]....
now on the server side I user linq to delete specified row and then submit changes to my DataContext and then DataBind() on my grid.
Problem is that sometimes standard ASPxGridView loading panel is shown for about 1 second ant then my row dissapears so it behaves properly but sometimes loading panel stops mooving. and I need to move mouse over my grid or click button so that my Grid is updated(row dissapears).
I have an ASPXGRIDVIEW which is binded to an SQL query.I added to the grid an additional COLUMNCUSTOMBUTTON.But what happens is, that for all the rows it put a link there.I am trying to find a way to add to this column a link (button) ONLY to specific rows!I am unable to understand how to do it
I have an ASPxGridView shown to the user with an edit command button. When the user clicks the edit command button the selected row will change into the edit form.In the edit form I have a control which when clicked will do a custom callback through javascript, the custom callback handler will then change a value on the selected row and call UpdateEdit() to save the changed value and return to the regular grid view layout.
However the new value is never saved to the underlying datasource, in fact if I debug the DataSourceControl's ExecuteUpdate method I see the updated value in the oldValues collection and the values collection has the original value.The javascript that is called from the control in the editform:
javascript:grid.PerformCallback("CloseOrder");
The custom callback handler which runs on the server:
protected void gdOrders_CustomCallback(object sender, ASPxGridViewCustomCallbackEventArgs e) {
if (e.Parameters == "CloseOrder") {
var row = gdOrders.GetDataRow(gdOrders.EditingRowVisibleIndex);[code]...
I am currently using DevExpress ASPxGridView and want the selection check box to show a redcross image on selection or empty when unselected. Is there any javascript library to do such a thing. If so can you provide me an example.
