How to enable checkbox column

Groove posted over 16 years ago

Hi I have used the following code to add a column to my ultrawebgrid however all the checkboxes show up as grayed out on my grid. Can someone please direct me how to make these checkboxes be able to be selected. I also use another method to customize all my grids but I dont think that could have disabled this option. I modify datagrid.DisplayLayout.selectTyperowDefault to selectType.single If anyone could help me out with this Id really appreciate it

Protected Sub dgPatients_InitializeLayout(ByVal sender As System.Object, ByVal e As Infragistics.WebUI.UltraWebGrid.LayoutEventArgs) Handles dgPatients.InitializeLayout

If Not Page.IsPostBack Then

Dim col As New UltraGridColumn()

col.Key = "CheckBox"

col.HeaderText = "Select Products"

e.Layout.Bands(0).Columns.Insert(0, col)

col.Type = ColumnType.CheckBox

col.IsEditable()

col.Width = Unit.Pixel(50)

End If

End Sub

I think you are missing the AllowUpdate="Yes" property. If you try that, it should work. I tried on mine by setting AllowUpdate="No" and the checkbox is disabled and when I set it to "Yes" it's enable again.

Hi I have one ultragrid which contains checkbox column, I used the following code to disable this column, but it did not work. The checkbox column was grayed but still can check or uncheck the checkbox in the column.

ultraGrid1.DisplayLayout.Bands[0].Columns["checkboxcolumnName"].CellActivation = Activation.Disabled;

I want to gray this column, also could not check or uncheck the checkbox in the column. Could you please help on this? Thanks a lot.

CSS Styles-

.CheckboxHeader_Checked

{
background-position: center 50%;
background-image: url(../images/CheckBoxChecked.gif);

}

.CheckboxHeader_Unchecked

{
background-position:center 50%;
background-image: url(../images/CheckBoxUnchecked.gif);

}

Grid Column should be this way -

<igtbl:UltraGridColumn HTMLEncodeContent="true" BaseColumnName="Covered" DataType="System.Boolean" IsBound="True"

Key="IsChecked" Type="CheckBox" Width="30px">

<HeaderStyle CssClass="CheckboxHeader_Unchecked" CustomRules="Background-repeat:no-repeat"

HorizontalAlign="Left" />

<Header Key="Checked">

<Image AlternateText="Select/Deselect" />

<SelectedStyle CssClass="CheckboxHeader_Unchecked" CustomRules="Background-repeat:no-repeat">

</SelectedStyle>

</Header>

<Footer Key="Checked">

</Footer>

<SelectedHeaderStyle CssClass="CheckboxHeader_Unchecked" CustomRules="Background-repeat:no-repeat">

</SelectedHeaderStyle>

</igtbl:UltraGridColumn>
