Collection view columns to be changed dynamically based on device orientation

sphinxg@usa.net — Thu, 07 Jan 2016 13:46:38 GMT

Hi All,

How to set number of columns for each row in collection view based on device orientation?
How to set the collection view cell height and width programmatically?
How to set the background color for each collectionviewcell using bindable style property?
Unable to trigger button click event in Collection header.

For example,

9 items to be bind in collection view then,
In Portrait mode, 2 columns to be shown and 3^rd row to be shown a single column
In Landscape mode, 3 columns to be shown
each cell has different color.
In native IOS (XCode), we have achieved above points by collectionViewLayout event.

Kindly share the details to achieve above points.

Best Regards,
Giridhar JG.

Remove column defined in aspx markup, from server-side

sinan.biondic@gmail.com — Tue, 16 Apr 2013 16:03:03 GMT

Hi,

I am trying to implement webgrid but the problem exists when I'm binding it to datasource. I have a stored procedure that returns some data.However, I don't know how many columns will be returned in that procedure, but I know the names of all columns that can be returned. So what I wanted to do, is to define all possible columns in aspx page, and in server-side PrepareDataBinding method remove columns from webgrid's column collection that don't have their match in datasource datatable that I'm binding it to.

This doesn't really work as I get an error stating that columne "XYZ" which is defined in aspx can't be found in datasource, although it was removed (I checked with debugger) in PrepareDataBinding event handler.

I presume this then is not possible, or am I wrong? The reason I am not creating columns from codebehind is simply that I would have to check datasource for every column to see if it exists and then create that column dynamically and add it to the column collection of webgrid. We did that in old version of our application and that PrepareDataBinding method has over 1600 lines of code, so I am looking for a better way of doing this. Please help me for the love of god!

This is my PrepareDataBinding method (column named "Check" is rowchecker column so i don't want it removed):

Dim dt As DataTable = CType(e.DataSource, DataTable)
 Dim grid As WebGrid = CType(sender, WebGrid)
 Dim colName As String
 For Each col As WebGridColumn In grid.RootTable.Columns
 colName = col.DataMember
 If Not colName = "Check" AndAlso Not dt.Columns.Contains(colName) Then
 grid.RootTable.Columns.Remove(col)
 End If
 Next

Webcombo clientside Row collection manipulation

sinan.biondic@gmail.com — Wed, 06 Mar 2013 14:17:28 GMT

I'm having problems retrieving row colection from webcombo. My combo is serverside binded, and in clientside pageload event I'm trying to get rows from combo. However i get nothing from method GetRows(). Applying filters is working fine but variable rows is null, and setselectedindex(1) does nothing.

function setComboFilter(idMenu) {
    var combo = ISGetObject('cmbGodina');
    var rows = combo.getRows();
    combo.ClearAdditionalFilters();
    combo.SetAdditionalFilters("[IdRedaMenu] = " + idMenu);
    combo.SetSelectedRowByValue(String(idMenu));
    combo.SetSelectedIndex(1);
}
