Gridview Unfiltered Rows

Hello,
I have looked and see that some people report that the isvisible property is true or false depending on whether the row is filtered.
I don't find this in my project.

I have a gridview that is bound to a datatable.
When the user filters the rows, we want to be able to iterate over the unfiltered rows and update a value in a cell.

Whenever I iterate over the gridview.rows collection, the gridviewrowinfo.isvisible is always true, regardless of filter state.

Can anyone point me to what I'm doing wrong?

Here is a snipit of code

Dim mCellPos As Integer = rgvItemsAndProps.CurrentCell.ColumnIndex

rgvItemsAndProps.BeginEdit()

For Each gr As GridViewRowInfo In rgvItemsAndProps.Rows

Dim y As String = gr.Cells(2).Value

If gr.IsVisible = True Then

gr.Cells(mCellPos).Value = _ItemPropGridClipboard

End If

Next

rgvItemsAndProps.EndEdit()

End If

GridViewColumn: FieldName vs Name - Incorrect documentation or bug?

According to the documentation for the GridView control (v2010.3.10.1215):

Gets or sets the name data source property or database column to which the is bound.

Gets or sets a string value representing the column's unique name in the Columns collection of the .

However, the code below does not display the value for SQL field "ProjectTitle"

   GridViewTextBoxColumn1.FieldName = "ProjectTitle"
       GridViewTextBoxColumn1.HeaderText = "Title"
   GridViewTextBoxColumn1.Name = "Title"

Instead, I have to set the property Name to the SQL field. The property FieldName can be anything.

GridViewTextBoxColumn1.FieldName = "Foobar"
       GridViewTextBoxColumn1.HeaderText = "Title"
   GridViewTextBoxColumn1.Name = "ProjectTitle"

Can someone explain to me which is correct?

By the way, I am binding to a SQLDataReader and AutoGenerateColumns is false.

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
Rui Silva

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.
