radgridview.Rows.Add does not return the row number

Hello,

I have some code that worked up until Q2 2010 SP1, which no longer works in Q3 2010. RadGridView.Rows.Add(...) used to return the row index of the added row, but in Q3 2010 it returns -1.

I have a hierarchical GridView and the following code:

private void SetupRadGridviewRelation()

{

GridViewRelation selfRelation = new GridViewRelation(this.radGridView1.MasterTemplate, this.radGridView1.MasterTemplate);

selfRelation.ParentColumnNames.Add("IdCol");

selfRelation.ChildColumnNames.Add("ParentIdCol");

this.radGridView1.Relations.Add(selfRelation);

}

public void LoadVariables

{

foreach (var varModel in list)

{

var rowNum = radGridView1.Rows.Add(varModel.Id, varModel.ParentId, varModel.VarName, varModel.VarValue, varModel.VarUnits);

radGridView1.Rows[rowNum].Tag = varModel;

}

Does anybody know of a solution. Is this a bug in Q3 2010?

Thanks.

RadDock Tabs

Good morning, i am having an odd problem when adding documentwindows to my radDock.
When i add a new tab, the tab allways open in the first position(left) of the first tab of my raddock, i have tried to change the position from "InFront" to "OnBack" but nothing changes. I use the radDock.AddDocument(documentWindow) method.

I want to know how i can make my tabs to open in the last position of the tabcontainer in my raddock instead of the first position.

Hope you can help me, best regards

Binding 2 combox inside radgridview

Hi All,

Actually i am new to telerik controls. Am using c#. My senario is - I have a radgridview. Inside that first column and second column are comboxcolumns. Users are allowed to add rows to gridview. And then click save button to save all the rows into database. Once i select the project from my first combo column all the tasks based on that project should get binded in second combocolumn of that radgrid. I am able to bind the second column based on the first column selected value. However, My problem is- Once i go to 2nd row in the gridview. the first row's secondcolumn which i already selected goes blank. And 2nd rows value is visble. When i move to 3rd row, the first 2 rows selected value in 2nd column goes blank. I mean at a time only one row value is visible for 2nd column. Anyone kindly provide me with the solution.

Hi everyone,

I have looked throught many of the forum posts and other documentations pages to see if there is a known solution to my problem... I did not find anything, but that does not mean that I did not overlook it. Anyway... I'm relatively new to the programming world and I am currently taking some programming classes as Lone Star's Montgomery College, where, in one of my assignments, I am to use the Telerik Rad Controls for Windows Forms. I downloaded and installed the trial software, but now that I have, I cannot create a new project in Visual Studio 2008. At first I thought that it would be a simple fix by just uninstalling and reinstalling, but I still cannot create a project, nor can I even open any of my old projects. When I try and open an old project, I simply get the error, "Unable to read the project file 'projectx.csproj'." If I try and create a new project, it acts like it is going to, but in the status bar at the bottom of the VS window, it says, "Creating project 'WindowsFormsApplication1'... project creation failed." I have a feeling that this is going to lead to me reinstalling VS but I'd like to avoid that if possible. Has anyone ever experienced this before or have a possible solution to help me out... unfortunately my assignments are due on a fairly strict deadline so the sooner I could get some help, the better... really, I'd just appreciate any kind of help at this point.

Thanks in advance,

C Jordan

Change border color of GroupBox header back to default

Hello,
I hope that someone can help me with this little issue.
I would like to change the color of a GroupBox Header back to the applied theme's default color.

I prgrammatically changed the border color with the following code to red to show an invalid user input (a kind of validation).


DirectCast(.rgrb_CountryOfOrigin.GroupBoxElement.Children(1).Children(1), BorderPrimitive).ForeColor = Color.Red

When the input is corrected the color should change back to its default value. Actually I use the desert theme.
Is there a possibillity to get a default color value for the assigned theme for the chosen control (eg GroupBox)?
If not, where can I find the theme values like colors etc?
Any help is appreciated.
Cheers Roberto

RowState Question

I've been unable to find specifics in the documentation for how the underlying data rows get updated when binding an editable grid to a dataTable. I have a problem where I retrieve a dataTable, call AcceptChanges() on it, bind it to the grid and the data shows properly. When the user edits row cells and clicks the save button, the RowState properties on the underlying dataTable are not set to Modified as they should be.

Is there an Update Mode property or something I'm missing? I've tried clicking elsewhere inside and outside of the grid after editing and the rowState remains unchanged. Ideas?

EDIT: The following code appears to fix it. It's called just before saving:

    
            foreach (GridViewRowInfo row in grd.MasterGridViewTemplate.Rows)  
        
            {  
        
                DataRow dr = ((System.Data.DataRowView)(row.DataBoundItem)).Row;  
        
                dr.EndEdit();  
        
            }

Is this the right way I should be handling this? Seems a little kludgy...Thx
