I want to make a column in my RadGridView clickable, such that clicking on a cell in a particular column opens another view with details for that row. I tried adding a button to the column, but I can't get the button to show the text from the actual column. I've got my RadGridView  bound to a System.Data.DataTable, and am defining the column as follows:

...but the button shows up as a skinny horizontal line with no text. It shows up as expected if I hard code the button content.

        private void gridView_DataLoading(object sender, Telerik.Windows.Controls.GridView.GridViewDataLoadingEventArgs e)
        {
            double width = 0;
 
            foreach (var col in gridView.Columns)
            {
                // None of these gives me the desired value
                //width += col.ActualWidth;
                //width += col.Width.DisplayValue;
                //width += col.Width.Value;
            }
 
            gridView.Width = width;
        }

Hi,

In my project, I have to create GridViewDataColumn for my RadGridView dynamically. When I finish creating my columns, I load data into my grid but the sort, filter and the grouping doesn't work :( I cannot see my filter button and if I try to drag a column header into the group panel, nothing happen.

Here is in my grid:

<telerik:RadGridView x:Name="radGridViewList" Margin="5 0 5 5" Visibility="Visible" RowDetailsVisibilityMode="Collapsed" FrozenColumnCount="1"

RowIndicatorVisibility="Collapsed" IsReadOnly="True" AutoGenerateColumns="False" CanUserFreezeColumns="False" Grid.Row="3"

CanUserResizeColumns="True" ShowColumnFooters="True" ShowGroupFooters="True" SelectionMode="Extended" IsSynchronizedWithCurrentItem="True" />

here is the code-behind:

static public void SetColumns(RadGridView pGrid, ColumnDescriptor[] pColumnNames)

{

if (pColumnNames != null)

{

SortedList<int, GroupDescriptor> grouping = new SortedList<int, GroupDescriptor>();

for (int iColumnIndex = 0; iColumnIndex < pColumnNames.Length; iColumnIndex++)

{

ColumnDescriptor oneName = pColumnNames[iColumnIndex];

Telerik.Windows.Controls.GridViewDataColumn oneColumn = new Telerik.Windows.Controls.GridViewDataColumn();

oneColumn.Header = oneName.ColumnName;

//Apply proper column display format.

switch (oneName.Format.ToUpper())

{

case "$":

oneColumn.DataFormatString = "C2";

break;

case "D":

oneColumn.DataFormatString = "yyyy'-'MM'-'dd";

break;

case "H":

oneColumn.DataFormatString = "HH':'mm";

break;

case "DH":

oneColumn.DataFormatString = "yyyy'-'MM'-'dd' 'HH':'mm";

break;

}

oneColumn.Width = new GridViewLength(1, GridViewLengthUnitType.Star);

oneColumn.ShowFilterButton = true;

oneColumn.IsSortable = true;

oneColumn.IsFilterable = true;

oneColumn.IsGroupable = true;

oneColumn.DataMemberBinding = new Binding(string.Format("ElementCells[{0:D}]", iColumnIndex));

oneColumn.TextAlignment = (TextAlignment)oneName.TextAlignment;

oneColumn.HeaderTextAlignment = (TextAlignment)oneName.TextAlignment;

//Create proper aggregate functions.

if (oneName.Agregation != AgregationFunction.None)

{

AddAggregateToColumns(ref oneColumn, oneName, string.Format("ElementCells[{0:D}]", iColumnIndex));

}

//Grouping field.

if (oneName.GroupingPosition != 0)

{

grouping.Add(Math.Abs(oneName.GroupingPosition),

new GroupDescriptor { DisplayContent = oneName.ColumnName, Member = string.Format("ElementCells[{0:D}]", iColumnIndex),

SortDirection = oneName.GroupingPosition > 0 ? ListSortDirection.Ascending : ListSortDirection.Descending});

}

//Add the column to the grid.

pGrid.Columns.Add(oneColumn);

}

//If grouping exist, add it to the grid.

if (grouping.Count != 0)

{

foreach (KeyValuePair<int, GroupDescriptor> oneGrouping in grouping)

{

pGrid.GroupDescriptors.Add(oneGrouping.Value);

}

}

}

}

Thank's
