[Solved] Horizontal scrolling

[Sajjad Shah]

How do I programtically scroll the scroll bar to the right in the grid...?

Hi Sajjad Shah,

You may use the ScrollIntoView method of RadGridView, passing the last column as a second parameter) .

I have tried this:

this

 

 

.RadGridView1.ScrollIntoView(this.RadGridView1.SelectedItem, this.RadGridView1.Columns[this.RadGridView1.Columns.Count - 1]);

 

 

and I get a targetparameter count exception. My requirement is to scroll the horizontal scroll bar to the extreme right beause therer are scenarios when the columns are more than what can be fit in a screen also number of columns dynamically change during what user has selected..

Thanks.

Hi Sajjad Shah,

I am sending you a sample project demonstrating the proposed solution.  Please take a look at it and let us know in case of any discrepancies according to your requirements.

OK. I do not get the error message anymore (that was the column count problem as I had few hidden columns)

Now, My scenario is more like this (change your code in mainPage.xaml in your sample to below):

<telerik:RadGridView.Columns>
<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" IsVisible="False" />
<telerik:GridViewDataColumn DataMemberBinding="{Binding Number}"/>
<telerik:GridViewDataColumn DataMemberBinding="{Binding Position}"/>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Country}" IsVisible="False" />
<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}"/>
<telerik:GridViewDataColumn DataMemberBinding="{Binding Number}"/>
<telerik:GridViewDataColumn DataMemberBinding="{Binding Position}"/>
<telerik:GridViewDataColumn DataMemberBinding="{Binding Country}"/>
<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}"/>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Number}" IsVisible="False" />
<telerik:GridViewDataColumn DataMemberBinding="{Binding Position}"/>
<telerik:GridViewDataColumn DataMemberBinding="{Binding Country}"/>
<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}"/>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Number}" IsVisible="False" />
<telerik:GridViewDataColumn DataMemberBinding="{Binding Position}"/>
<telerik:GridViewDataColumn DataMemberBinding="{Binding Country}"/>
<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}"/>
<telerik:GridViewDataColumn DataMemberBinding="{Binding Number}"/>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Position}" />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Country}" IsVisible="False" />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" IsVisible="False" />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Number}" IsVisible="False" />
<telerik:GridViewDataColumn DataMemberBinding="{Binding Position}"/>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Country}" IsVisible="False" />
</telerik:RadGridView.Columns>
</telerik:RadGridView>


After hiding few columns. When I click the scroll to the right button. it does not do anything. Although it does appear that scrollbar should scroll to the right..

Hi Sajjad Shah,

This is the expected behavior as you are trying to scroll to an element that is not visible. Still, the fact that the column's property IsVisible is set to "False" does not mean this column is not a part of the Columns collection. What you can do is to check if the column is visible before scrolling to it. For example:

private void Button1_Click(object sender, RoutedEventArgs e)
        {
            for (int i = this.playersGrid.Columns.Count - 1; i >= 1; i--)
            {
                if(this.playersGrid.Columns[i].IsVisible)
                {
                    this.playersGrid.ScrollIntoView(this.playersGrid.SelectedItem, this.playersGrid.Columns[i]);
                    return;
                }
            }
        }

 

All the best,
