TabPrimitives Visible and Dropdown

[Qingde Shi]

Hi,

How to show or hide TabPrimitives based on if there are tabs that are not shown when tabs are in single line mode, and how to make the TabPrimitives's dropdown to only show the tabs not shown?

Thanks,

Hi Qingde, 

Thanks for contacting Syncfusion support. 

We have analyzed your query and prepared sample to meet your requirement. In this sample we have changed the visibility of the TabPrimitivesHost to true, if the total width of the TabPages are greater than tabcontrol’s width. Otherwise visibility of the TabPrimitivesHost will be false. Please download the sample for the same from below location, 

Sample: http://www.syncfusion.com/downloads/support/directtrac/general/ze/TabControlAdv_Sample_TabPrimitives_Visibility_Resolved612614567.zip 

Please find the code example to update the visibility of the TabPrimitiviesHost from below table, 

        private void UpdatePrimitiveHostVisibility() 

        { 

            int TabRectWidth = 0; 

            if (this.tabControlAdv1 != null && this.tabControlAdv1.TabPages != null) 

            { 

                for (int i = 0; i < this.tabControlAdv1.TabPages.Count; i++) 

                { 

                    TabRectWidth += this.tabControlAdv1.GetTabRect(i).Width; 

                } 

                if (this.tabControlAdv1.Width < TabRectWidth) 

                { 

                    this.tabControlAdv1.TabPrimitivesHost.Visible = true; 

                } 

                else 

                { 

                    this.tabControlAdv1.TabPrimitivesHost.Visible = false; 

                } 

            } 

        } 

If we misunderstood your query please provide more details about your requirement with sample. This would help us to provide the solution at earliest.

Great! Thanks. It gave me ideas on how to solve this issue. Tabgap, TabVisible should be considered as well.

Hi Qingde, 

Thanks for your suggestions.  

We have modified our sample based on your considerations. In this sample, we have changed the visibility of the TabPrimitivesHost based on the TabVisible property and TabGap property along with TabPages width.
