I have a SP that is building a table and the results from that table on the fly. So when I apply it to a datgrid, there are no columns to select, because they won't be created until the program is running.
Is there a way to display the data after the program is running?

View 1 RepliesI am using Visual Studio 2008 Shell and SQL Server 2008. Currently I am able to display DataGrid. But now I have a new requirement where I have to enable a text search in one of the columns. How can I implement this? I tried implementing a solution I found online, but I'm still getting errors. Please be gentle; I am a novice VB.Net programmer And since this is Shell edition and source data is on a different machine which I do not have direct access to, I am not able to debug at all.
Below is all of my code. Note that currently I cannot even view it as an ASPX page since there are still a couple of errors.

I'm trying to rig up a ComboBox with a Datagrid dropdown in WPF. I need the the code to be done programmatically and contained in the codebehind. Here's what I've got so far:

This code produces a ComboBox that contains a DataGrid with two columns and seems to look fine. Although when you click on the ComboBox and select one of the rows in the DataGrid the selection in the ComboBox doesn't work properly. (It just shows the colum headers.) I want the value in the first column of the selected row to appear as the ComboBox selection.

I would like to be able to programmatically create DataGridTemplateColumns based on my data source. For example, if my source has a date in a particular column I would like to be able to utilize a Datepicker control. I know this is easily accomplished with xaml and a DataGridTemplateColumn at design-time, however, how would I accomplish this at run-time?
Is my best option xamlreader.load or a more traditional route like:
Dim TempCol As Microsoft.Windows.Controls.DataGridTemplateColumn
I have not had any success with the latter.

View 3 Repliesi have a form with a textbox, datagridview, tabcontrol. I use the tabcontrol to create an indexed view of the datagrid using the alphabet to filter the records to show the respected fields according what tab was selected. The textbox I have on the form is databinded to a field of a table in the database. The datagrid is also databinded to the same table in the database. The binding on the textbox breaks when I press on a tab to change the filter type. On the tabcontrol.selectedindex event I have this code to filter and fill the datagrid is: conn.Open()

I have on my form two datagridviews that correspond to the same table. They are both databound. They have been created automatically through dragging them from the datasources windows.One is datagridview and the other datagridview1. When ever I navigate through a datagrid the corresponding row on the other grid changes as well. I do not want this. Also I want to be able to fill and use each datagrid indepentent from each other. To fill a datagridview on load I use this code
Me.AllServicesTableAdapter.workstation(Me.Database2DataSet.AllServices)This code does not let me choose which datagrid to fill.
I have a search form on that will be pulling search template queries from a table in the underlying (an Access db on a share). The search form has a calendar control for filtering by date range, a listbox containing the names of the search templates, a second listbox which lists the fields in the selected template, and then some controls which show/hide themselves depending on which field is selected so that the user can pick a field and enter it's unique criteria in the appropriate control for filtering. Below these controls is a DataGrid, which will obviously display the results.
The problem is how to dynamically "transform" this DataGrid to display the selected search template. These templates do not represent tables in the underlying; rather they represent preconstructed SQL queries (stored in a table) which are essentially SELECT queries with joins and no WHERE clause (so they are the results of multiple tables joined together by their keys).
To be honest, I'm having trouble even generating the LINQ queries to represent these template dynamically, but that's not as important, since I can manually translate the SQL queries into LINQ. This is definitely not the preferred method, as the whole point of putting these templates in a table, rather than code, was to allow for future additions without rebuilding/redistributing the application interface.
what are the differences between the WPF Datagrid included in the .NET Framework 4.0 versus the Datagrid included in the out-of-band WPF Toolkit? I understand that the toolkit version was released first, and targets the .NET Framework 3.5 SP1.
I needed a WPF datagrid quick and have utilized the toolkit version in my applications. I'm considering moving the application to .NET 4.0 and am wondering what the pros/cons will be in changing out my existing datagrids for the new ones.
I have one data grid which contains a column which contains long string values. When I edit it, the text box which appears is very small. I want to increase the length of text box.
