Making particular cells editable in an event
posted

Hi all,

         I have developed a windows form application in which I have used Infragistics' UltraGrid Control. I have populated the grid by binding the data at run-time with a dataset. I have a dropdown column in my grid and I have used an event handler for that column once the value is changed from the dropdown(celllist_select event). Now I need to make some particular cells of  the row which I have selected(ActiveRow) as editable, once the dropdownlist item is changed. I will just give a tabular representation of my requirement.

 

ID Amount Formula Projected Value1 Actual Value1 Projected Value2 Actual Value2 Projected Value2 Actual Value2
1 5000 Linear 1000 2000 500 250 1000 3000
2 5000 Manual 100 200 500 1000 400 800

Now in this table, as you can see I have a column called "Formula"  which is a dropdownlist column containing items such as Linear,Manual,Bell Curve,etc; In the second row, I have selected the formula as Manual. So, once I select Manual, I want all the projected values of the 2nd row alone to be editable. Rest of the cells shouldn't be editable. How to achieve this? I don't want to use initializelayout to achieve this functionality. Any help rendered would be of great use.

    Hi,

    You have to call the below code while initializing the grid.

     <igtbl:UltraWebGrid ID="GridName" runat="server"
                                                    AutoGenerateColumns="false"
                                                    DisplayLayout-ActivationObject-BorderColor="Black"
                                                    DisplayLayout-ActivationObject-BorderStyle='Solid'
                                                      oninitializerow="GridName_InitializeRow"       >  

     Write the following code in code behind.

    protected

     

    void GridName_InitializeRow( object sender, Infragistics.WebUI.UltraWebGrid. RowEventArgs e)

    {

     

    for ( int i = 0; i <= e.Row.Cells.Count-1; i++)

    {

     

    if (i > 9)

    {

     

    //editing paricular cell

     

     

     

    e.Row.Cells[i].AllowEditing = Infragistics.WebUI.UltraWebGrid.

     

    AllowEditing

    .Yes;

    e.Row.Cells[i].Style.BackColor = System.Drawing.

     

    Color .White;

    // "white";

    }

     

     

    else

    {

    e.Row.Cells[i].AllowEditing = Infragistics.WebUI.UltraWebGrid.

     

    AllowEditing

    .No;

     

    Hope.it helps :-)
