View 1 RepliesWeb Forms :: WebPart Drag And Drop?
Feb 17, 2011I cannot get the Drag and Drop functionality of Web Parts is to work. I have a very simple test page with two WebPartZones.. In the OnInit method of the code behind I put the page in design mode. In the first zone I have a textbox.At runtime the text box renders as a web part. When I hover over the web part header my mouse pointer changes the 'move' pointer, but I cannot drag the item. I do not see it dragging and the part never moved. I am using Visual Studio 2010 with IE 8. I have tried IE8 in compatibility mode and regular mode. The results are the same. Here is the markup from my test page:
<form id="form1" runat="server">
<div>
<asp:WebPartManager ID="WebPartManager1" runat="server">
</asp:WebPartManager>
<asp:WebPartZone ID="LEFT" runat="server">
<ZoneTemplate>
<asp:TextBox ID="tb" runat="server" />
</ZoneTemplate>
</asp:WebPartZone>
aa
<asp:WebPartZone ID="RIGHT" runat="server">
</asp:WebPartZone>
aa
<asp:EditorZone ID="EditorZone1" runat="server">
</asp:EditorZone>
</div>
</form>
Here is the code behind:
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
WebPartManager mgr = WebPartManager.GetCurrentWebPartManager(this);
mgr.DisplayMode = WebPartManager.DesignDisplayMode;
}
What am I missing?
Web Forms :: Binding A Drop Down List
Mar 3, 2010I have a Drop Down List which I need to bind to the database. Here is the situation. I am not using a SQLDataSource. It is built on the n-tier application. The datasource of the dropdown is referring to a method in the C#class. That method has a generic array list which populates information into the arraylist. The Arraylist is the parameter that is returned to the DropDown List.
I have also set the Text property of the Drop down list
Text='<%DataBinder.Eval(Container.DataItem,"Employee_ID")%>'>
However, it is not populating the DropDown list, what should I do?

Web Forms :: Programmatically Drop Down A DropDownList ?
Mar 7, 2011I have a text box into which the user types a string of characters. When they have completed this search string they click on a button which then displays the number of matches found and populates a DropDownList control with them. The user has to then drop down the control to see the matches, but it would be much slicker to drop down the control automatically for them, especially as they sometimes don't notice there is more than one match and, therefore, select the wrong one.

View 1 RepliesWeb Forms :: Convert Drop Down String Values To Int
Feb 1, 2010i have two tables which are related (school and departments). school_table (school_id, school_name) and department (dept_id, dept_name, school_id). page 1 creates the school - i take school name via textbox and school_id is auto generated in database. so informatics = 1, science = 2, etc page2 creates department - i take department name via textbox, dept_id is auto generated, and now i need a way to take school_id from this page to create the relationships (so we know which department belongs to which school). however, i don't really want the user to enter school Id that gets auto generated in the schools_table, instead i want to create a drop down list and populate it with the school_name values taken from page one. but these drop down values should represent an int value behind the scene since it needs to go to school_id (department_table) but how can i convert the drop down values from string to int so that if i enter informatics from drop down the value will be 1 in the school_id column?
