Hi There,

 

This call is only a nice to have, it is not critical at all. It is just a slight annoyance when building the Grid's columns - especially when there are many columns to adjust. My workflow is usually as follow. 

 

Add all the columns needed, then after that I will run through all the columns and want to set the widths. But my speed is broken because I can't tab between the 3 width properties: Width, Min Width, Max Width. I have to click to put focus the the next value.

 

If possible, please can you correct the tab indexes?

 

Thank you

Kind Regards

Ben

 

PS. You may close this ticket immediately - this is only a request.

  1. Filter the column "code" to show only "(Blanks)"
  2. Hit the "Save Layout" button to save the layout into a string
  3. Hit the "Load Layout" button. The row is gone

Please refer to the attached sample project and follow the steps from the grid file:

Steps to reproduce:
1. Filter the checkbox column to only show unchecked rows
2. Enter "5" for filtering the Name column
3. Click the checkbox column on the bottom row
4. Remove filter value in the Name column
This will result in the unrelated record showing as checked. Scrolling or changing sorting may refresh the cell. If the  filter is cleared by using the No filter menu option, the problem is not observed

I have three grids.

Two of the grids (B & C) are on the same tab and the other (A) on a different tab.

Only one tab can be visible at any one time, so you can either see and interact with the single grid (A) or the other two grids (B & C).

I need to be able to select a row in C (based on a criteria) when you click on a row in A or B.

Grid C has paging enabled.

I can successfully select the desired row in C when I click on a row in B and see the paging change to show the selected row.

But, when I click on a row in A and find a matching row in C, the row seems to get selected but the paging does not move to where the selected row is.

If you define which columns to be printed on separate pages and try to use the Print Settings dialog to change the orientation for example, the multi-page printing gets lost:

        Me.RadGridView1.DataSource = Me.CustomersBindingSource

To reproduce:

1. Bind a RadGridView to the Northwind.Products table

2. Enable the header checkbox for the Discontinued column

3. Set the ReadOnly property either for the grid or for the specific column.

The header checkbox is not allowed to be toggled. However, you can toggle/untoggle it which affects all the data rows.

Currently, due to the specificity of the internal implementation for this scrolling behavior, the possible solution that I can suggest is to hide the row header by setting the ShowRowHeaderColumn property to false

this.radGridView1.ShowRowHeaderColumn = false;

Hello everyone,

We found one problem with the  RadListFilterPopup (WindowsForms)

When we use one specific type of keyboard (with numeric and it has char '.' in it) the char '.'  make the same error.
