try 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().
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 am new DEVEXPRESS controls . In my project i need to work with ASPxGridView , where i need to make all the row value clickable (for a particular record). When clicked it takes the user to the next page where it displays all the information regarding that record.
give me some insights regading how to approach this problem and how to use rowClick event
I am trying to build a custom composite control, which allows me to add custom content to each child control. It's a similar concept to what you have with a GridView and TemplateColumn. The markup used to place the control on the page would end up being something like this:
[Code]....
I have the code below, which allows me to put that markup on the page without throwing any errors, and it renders all the correct HTML, except it doesn't render the contents of the ColumnTemplate. I have replaced the Render() code with a comment because it's quite long winded and doesn't add anything important here:
[Code]....
I have tried to follow examples on MSDN and other forums but I can't make this work. I think I'm missing the code to render the contents of the template, but I don't know how to hook that up.
I want to know if I can invoke AspxGridView update. I catch a data on AspxGridView Focused Row in server side. And if this data equles 0, I want to invoke update for this row. Else if this data equles 1, i want to invoke new row. Is it possible?
I 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?
Im using aspxPopupControl with AspxGridView in it. Is it possible to set control to fill all popup cause now when I try to resize that popup there is a lot of free space at the top and bottom when I increase width od the popup.
I 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:
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:
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?
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?
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)
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?
I want to access selected value of GridViewDataComboBoxColumn in server side at GridViewUpdated event. Do you have any idea about how can it be?Here is columns of AspxGridView
I'm using DevExpress ASPxGridView edit form, using default edit form. However when I open the edit form in IE6 and click "update" to insert the record, it causes a JavaScript error that says "type" is null or not an object". However it works fine in IE7. I am puzzled and unsure of how to resolve this. Code is below.
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 have some (probably very basic) questions about developing custom controls. I am wanting to derive a set of button controls, and the first one I have started on is a "DeleteButton", that has a additional property (DeleteConfirmationText) that is built into the OnClientClick attribute. To get that added, I overrode the Render method as follows:
[Code]....
This all works well. Now, I will add some logic to make sure that there is some text in the DeleteConfirmationText property, but that isn't the intent of my question. What I am also wanting to do is to override some of the default property values, so I added that to the default constructor:
[Code]....
Now, in the designer in VS2008, and I look at the properties for the control, there isn't a default value shown in the "Properties" section, and the Causesvalidation still shows the underlying classes default value of "True". As well, in design mode, where the GridView control that containse my DeleteButton control would be displayed, there is an error box "There was an error rendering the control. 'Are you certain you want to delete this attorney?' cound not be set on property 'DeleteConfirmationText'. Here's the markup where I am defining the deletebutton control:
