Errors

Hi
I am facing this message once I run my project(see the attached Pic error1), rather than it takes around 5min and more just to initializing for opening at the first time

Further more it is very slow in developing and some times the system give me an error in manifest memory when I try to add any thing new or modify an existing control ,

Error 1 Problem generating manifest. Insufficient memory to continue the execution of the program.

Moreover sometimes when I add new things it did not appear in the running stage even thought it is their in the design?

Sometimes also I need to close the project and open it a gain just to see the modification I added otherwise it will not be shown at the same time

Am using telerik winforms wpf Q3 2010 in Visual Studio 2008

Thanks in advance

I use datasource to bind the value to my datagrid. I able to sort the value from assending to desending....
The datagrid also show me correctly from a - z become z - a.

Dim FileN as String = ""
For i = 0 to RadGridView1.rowcount - 1
FileN = RadGridView1.Rows(i).Cells(0).Value
msgbox(FileN)
Next

after desending it i can't the get "z" as the first value... it still give me the value "a".
May i know how to do that? it's need urgently because i change the current .net datagrid to telerik gridView for user.
Thank You!

Data exception error - why?

Hi,
I have a radgrid with the data loaded:

OleDbDataReader reader = cmd.ExecuteReader();

radGridView1.DataSource = reader;

After editing a row, before the MasterTemplate_CellEndEdit fires (where I would manually update the changes in the table) I get the errormsg shown in the picture. Any clues?

Code snippet for radGrid based on table

Hi,

I have an access db with say 20 tables and a radDropDownList showing them. On the event SelectedIndexChanged of the radDropDownList I would like to reconstruct radGrid layout so that the radGrid now reflects the selected table and its data.

It would be like simulating ms Access but not needing access installed and being able to make a few minor data changes.

Does anyone have something like this they care to share?

Thanks,

Karl

Remove Child From GridView

I have a GridView in which the child is loaded manually via a RowSourceNeeded event. I am using the ChildViewExpanded event to detect that the child is being collapsed (!IsExpanded). As part of the collapse, I would like to delete all of the child rows, thus forcing another RowSourceNeeded event (Data refresh) when the child view is expanded. I have tried the following and many others without success.

private void radGridViewDatabases_ChildViewExpanded(object sender, ChildViewExpandedEventArgs e)
        {
            if (e.IsExpanded)
            {
                e.ChildRow.Height = Math.Min(90 + (e.ChildViewInfo.ChildRows.Count * 18), 500);
            }
            else
            {
                if (e.ChildViewInfo.HasChildRows())
                {
                    foreach (GridViewRowInfo oGridViewInfo in e.ChildViewInfo.Rows)
                    {
                        oGridViewInfo.Delete();
                    }
                }
            }

            return;
        }

Any ideas?

Thanks in advance

Lat/Lon Custom Editor

Hi,

I have an application that has latitude and longitude values in cells in a GridView. I need to have the user edit these values. Currently, I have them as individual cells and the user can edit them individually by entering new values. What I would like to do is extend this editing so that the values can be set by clicking a location on a globe. The lat/lon value would then be returned via an event and the values in the cells updated accordingly.

I'm not sure how to do his if I have separate cells for the lat/lon values.

Does anyone have any suggestions on how to proceed?

Thanks.

Ken...
