hi,
I'm trying to bind data table to gridview without any success.

My gridview contains a few columns like Date (DateTimeColumn),  Name (TextBoxColumn),  User: (ComboColumn)...

when i read my data from server to dataTable its contains (iDate, iName, iUser, and a few more columns,  more than the gridview contains)  
and as you can see the names of columns are differents.


Best regards,
Roy

It's a control on ASP.NET, will it be available for Winforms at some point?

Using the VisualStudio2012Light theme when a property is edited in the property grid the row stays highlighted after the edit.  Then if you scroll that item out of view and scroll back to it then the highlight will go away.

I have a column that is created programmatically and is set to a complex data type.  I need the data type to be complex because I need to override the CompareTo method.  I also want to be able to use textual filtering on this column, via the ToString() method of my type.  When I try to filter on this column, a ParserException is thrown and my program crashes.

consider the following example:

class MyCellType
{
      public string myName;
      public string myParentName;

      public override string ToString()
      {
            return myName;
      }

      public int CompareTo(Object obj)
      {
            //my compare function which sorts children underneath their parents...
            if ( myParentName == ((MyCellType)obj)myParentName )
            {
                 return String.Compare(myName, ((MyCellType)obj)myName);
            }
            else
            {
                return String.Compare(myParentName , ((AdminUnitCell)obj).myParentName );
            }
      }
}


//... code that initializes the grid and a data table

GridViewTextBoxColumn column = new GridViewTextBoxColumn();
column.Name = "MyColumn";
column.HeaderText = "MyColumn";
column.FieldName = "MyColumn";
column.DataType = typeof(MyCellType);
myGrid.MasterTemplate.Columns.Add(column);

myDataTable.Columns.Add("Title", typeof(MyCellType));

//...

myGrid.DataSource = myDataTable;

I looked for a solution to this problem but I could not find a definite answer.  Is textual filtering possible on a complex data type via its ToString() method? If not, then can we get this feature (bug fix) in a future release?   I find it difficult to believe that no has ever had a column with a complex data type on a filter-enabled grid and thus experienced the same crash that I am getting.

Any help would be appreciated.

Recently the Telerik Academy held a free Front-end development course, It included an in depth tutorial on HTML, CSS, Javascript and working with CMS. It will include lectures on sth

  RadTreeNode node = new RadTreeNode();
                rdTvSearch.Nodes.Clear();
                string url = string.Empty;
                foreach (DataRow row in MyDataTable.Rows)
                {// and this check if send a PID , or a parent id to make fileration.
                    // if (row["ParentID"] == DBNull.Value || parentid != null) //That the regular case when loading the tree with the Level one parent , that dunt has any parent.
                    //{
                    if (row["IsChild"].ToString() == "True")
                    { node.Image = TechTouch_Point.Properties.Resources.file2; }
                    else
                    { node.Image = TechTouch_Point.Properties.Resources.folder1 ; }
                    node = new RadTreeNode(row["NameArabic"].ToString() + ' ' + "_" + ' ' + row["Number"].ToString(), row["ID"].ToString());
                    node.Attributes.Add("number", row["Number"].ToString());

                 //   node.ExpandMode = TreeNodeExpandMode.ServerSideCallBack;
                    node.Expanded = true;
                    node.Attributes.Add("name", row["NameArabic"].ToString());
                    node.Attributes.Add("child", row["IsChild"].ToString());
                    node.Attributes.Add("treenameid", treenameId.ToString());
                    
                    rdTvSearch.Nodes.Add(node);

Hi,

Hi,

I am upgrading all controls of my C# winform app to Telerik. I couldn't find drawitem event in RadDropDownList.

Here is the code of combobox drawitem event:

private void cbMyCompanyList_DrawItem(object sender, DrawItemEventArgs e)
{
 
e.DrawBackground();

DataRowView drv = (DataRowView)(cbMyCompanyList.Items[e.Index]);

int CoID = (int)(drv["CompanyID"]);
string CoNum = (string)(drv["CompanyName"].ToString());

...........

using (SolidBrush sb = new SolidBrush(e.ForeColor))
 {
      e.Graphics.DrawString(..., e.Font, ..., ...);
 }
}

How could I translate this to Telerik?

Thanks in advance!!

Is it possible to get the name of the printer that the user selected when printing a PDF document using the RadPdfViewer?

I have some questions about the RadRichTextBox.

How do I data bind the content of the RadRichTextBox to a datatable, and how could this be accomplished?

What is the most appropriate field type in an sql database for the content to be stored in?

If I cannot data bind to a datatable then how can this functionality be created?

Thanks in advance
