get the datafield from the RadGrid.column

[Mark]

Hi,  radgrid
    I wish to get the value of the datafield of a column programmatically, however when I type Columns[0]., intellisence
does not show the datafield option. I have to use the Uniquename instead, however this will not always be the same as the datafield and thus could cause problems. Please help.




GridFilteringItem item = MasterTableView.GetItems(GridItemType.FilteringItem)[0] as GridFilteringItem;
                
             
                for (int i = 0; i < Columns.Count - 1; i++)
                    {

                    Type colType = Columns[i].DataType;
                    Telerik.Web.UI.GridColumn column = Columns[i];
                    string colName = MasterTableView.Columns[i].UniqueName;

                    if (colType == typeof(System.String) && (Columns[i].Visible))
                    {

A generic GridColumn object does not contain the DataField property. You will have to cast this column as a GridBoundColumn in order to retrieve this information:

GridBoundColumn myColumn = (GridBoundColumn)RadGrid1.Columns[0];
String myString = myColumn.DataField;

Ok Schlurk,
    After getting the DataField name using the code

GridBoundColumn myColumn = (GridBoundColumn)RadGrid1.Columns[0];

String myString = myColumn.DataField;

how will i dynamically set the column name to the corresponding grid control?

string errMsg = string.Empty;

CarFamilies listDAL = new CarFamilies();

CarFamiliesDTO ListDTO = new CarFamiliesDTO();

ListDTO = listDAL.GetCarDetails(ref errMsg, ListDTO);

DataTable dt1 = ListDTO.dtCarFamilies;

grdDynamic.DataSource = dt1;

grdDynamic.Columns[0].HeaderText = "CAR CODE";

grdDynamic.Columns[1].HeaderText = "CAR NAME";

GridBoundColumn myColumn = (GridBoundColumn)grdDynamic.Columns[0];

String mystring = myColumn.DataField;

GridBoundColumn myCol = (GridBoundColumn)grdDynamic.Columns[1];

String mystr = myCol.DataField;

grdDynamic.DataBind();

Schlurk, i will be glad if you help me to sort out my problem as soon as possible

Hi,

If you use autogenerated column they will take the name of the DataField as unique name. You could hook the ColumnCreated event of RadGrid and change other properties if necessary.

On the other hand you could define the columns programmatically as shown in this help topic.

I do not see where you are using the mystring and mystr variables? What is your final goal?
