key not found – Parameter name: key

When I run the following code (VB.Net) I get the error message:  key not found Parameter name: key  when I try to attach the [Grid] to a [Tab]

 Is this a "key" property with the [Grid] or with the [Tab] that it resides on?

I'm dynamically adding the [Tab] and the [Grid] at runtime.

If I insert a [Grid] on a [Tab] at design and run similar code to load my data, I do not get this error message.

What have I missed?

 ==================================================================

Dim OptiSaveViewGroup As New clsGroups()

'……………………………….Dim osvgGroupDataSet As DataSet = OptiSaveViewGroup.GetOptiSaveViewData2(CInt(txtRunNumber.Text))

'————————————Dim Grid1 As UltraWinGrid.UltraGrid

Grid1 =

New UltraWinGrid.UltraGridWith Grid1

.DataSource = osvgGroupDataSet

.DisplayLayout.Appearance.BackColor = Color.White

.DisplayLayout.Appearance.BorderColor = Color.DarkGray

.DisplayLayout.Appearance.Key =

"Tab2"

.DisplayLayout.Bands(0).HeaderVisible =

True

.DisplayLayout.Bands(0).Header.Caption =

"OptiSave Report"

.DisplayLayout.Bands(0).AutoPreviewEnabled =

True

.DisplayLayout.AutoFitStyle = UltraWinGrid.AutoFitStyle.ResizeAllColumns

.DisplayLayout.ScrollBounds = UltraWinGrid.ScrollBounds.ScrollToFill

.DisplayLayout.ScrollStyle = UltraWinGrid.ScrollStyle.Immediate

.DisplayLayout.Override.AllowRowFiltering = DefaultableBoolean.True

.Dock = DockStyle.Fill

End With

UltraTabControl1.Tabs(ActiveTabName).TabPage.Controls.Add(Grid1)

Grid1.Refresh()

 

Thanks ahead of time.

That error usually means you are trying to refer to an object in a collection by a key that does not exist in the collection. My guess is that your UltraTabControl does not have a tab whose key is ActiveTabName.  

Your right Mike, I actually figured that out after I sent the blog to ya.

Thanks for your help.

Hi Mike,

Hi,

This error message indicates that something in your code is trying to reference an object in a collection using a key that does not exist.

From the Call Stack, it appears that you are handling the ToolClick event of a tool in UltraToolbarsManager and which calls intothis method.

Allscripts.TouchWorks.Workspace.ChartViewer.ChartViewerControl.m_ToolbarsManager_ToolClick(Object
sender, ToolClickEventArgs e)

And this code is ultimately trying to reference a tool with a non-existant key when it gets to this method:

at Allscripts.TouchWorks.Common.PanelOrderViewer.UpdateButtonsState()

Hi Mike,

Thanks for the quick response. So, do I need to check for the existence for the following:

this.popupPrintFax.Tools["btnPrintReq"].SharedProps.Enabled = false;
this.popupPrintFax.Tools["btnFaxReq"].SharedProps.Enabled = false;
this.popupPrintFax.Tools["btnPrintRes"].SharedProps.Enabled = false;
this.popupPrintFax.Tools["btnFaxRes"].SharedProps.Enabled = false; 

Could you give me a sample Psuedocode for this.

Nothing to it:

if (this.popupPrintFax.Tools.Exists("btnPrintReq"))
                this.popupPrintFax.Tools["btnPrintReq"].SharedProps.Enabled = false;

Hi Lava,

This exception indicates that you are trying to reference a Cell in the grid using a Key of a column that does not exist. You should probably check out that code and see why you are doing that. Maybe it's an unbound column and you are trying to access the cell before that column was added? If so, then a simple solution would be to use the Exists method to make sure the cell is there before you try to access it, just as I did in the sample code above.

Thanks   Mike :)..I will look in to that ..

Hi Mike ,

              There is an another issue , where  when I am tabbing it is giving me a "Object reference not set to an instance of an object  exception" ..

below is the exception details , when I debugged I got to know that  "obj.FocusControl  " is null ,pls guide me in this  on setting the Focus Control  property with some thing from the code.

Exception Message:

Object reference not set to an instance of an object.

Hi Lava,

I'm not sure how I can help you with this. According to the call stack, the exception is occurring in the KeyDown event handler for your grid. So it's your code that's raising the exception because you are trying to reference a property of an object that is null. You need to find out why that object is null or add a null check so that code does not get called when there's no object to call the method on.

I'm getting something similar, can you decipher?

According to this, the grid is trying to get the ScrollTipField column and the name you specified for the ScrollTipField does not exist in the band.
