View 7 RepliesForms Data Controls :: How To Bind Grid View Columns Dynamically
Feb 9, 2010I am developing an application using ASP.NET with C#.NET.in my application i have a gridview control and radobutton list having the values as Manufacturer and Distributor. based on the radiobutton selected value,the gridview will bindedup.
i am using SQL SERVER 2005 as backend server. in my database i have one table with columns as
1.mfropendate
2.mfrclosedate
3.mfrawarddate
4.distopendate
5.distclosedate
6.distawarddate
My gridview has 3 columns as Opendate,closedate,awarddate.
if user select the radiobutton as manufacturer,only mfropendate,mfrclosedate,mfrawarddate have to bind. and if user select the distributor the remaining 3 fields will have to bind. for that i had write a storedproc as create procedure sp_GetDraftBids as begin select mfropendate as opendate,mfrclosedate as closedate,mfrawarddate as awarddate, distopendate as opendate,distclosedate closedate,distawarddate awarddate from draftbids end GO
i.e i had taken the alias names for that fields so that i will bind the only 3 columns to grid view as opendate,closedate,awarddate.
My gridview code is
[Code]....
here i had taken the same alias names as i have to bind only 3 columns to gridview.when i run my application i am getting the records in data table with column names as opendate,closedate,awarddate,opendate1,closedate1,awarddate1.i.e it does not allow the same alias name.
for two radio button conditions i.e for manufacturer and distributor the gridview binded with opendate,closedate and awarddate columns as i had binded the gridview boundfields withat names.
but when user select the distributor radiobutton i have to bind the opendate1,closedate1 and awarddate1 to the gridview. for that should i can i change the storedproc are any other solution is there?

Forms Data Controls :: Bind A Dropdownlist Which Is Present Only In The EditItemTemplate
Jun 15, 2010I am handling the row databound event. I need to bind a dropdownlist which is present only in the EditItemTemplate.
So it is throwing:
DropDownList ddlAccountingPeriod = e.Row.FindControl("ddlAccountingPeriod") as DropDownList;
UIControlHelper.BindApprovalPeriod(ddlAccountingPeriod);
this throws a null exception as the dropdown is not present in the ItemTemplate.
Is there a way to check whether it is itemtemplate or edititemtemplate.

Forms Data Controls :: How To Put Tooltip In Dropdownlist Bind With Sqldatasource
Mar 4, 2010I have a dropdownlist that's being populated from a SQL datasource. I would also like to have a tooltip for each dropdownlist list item on mouse over. I found the example below which adds a title attribute for each list item using the listitem text as a tooltip but I want to make the title/tooltip value another field in the database. In other words,
item.Attributes.Add("title", someotherdatabasefield);
The end result would be something like this where the text for 'title' comes from the database
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True">
<asp:ListItem Text="CompanyName1" Value="1" title="a really great company" />
<asp:ListItem Text="CompanyName2" Value="2" title="a really bad company" />
</asp:DropDownList>

Forms Data Controls :: How To Bind A DropDownList Inside A Repeater
Oct 29, 2010I am new to ASP.NET, trying to learn it. I am using ASP.NET 3.5 with VB for scripting. Also read some books. I just can't figure out how to bind a DropDown List inside a Repeater Control. I saw a few examples but none were clear enough and explained all the details. I want to populate the Drop-Down using values from a Database inside the repeater.
I also read this article [URL] but still can't understand how to bind dropdown in a repeater.
I want to display 2 things inside the Repeater Control.
1. User Selected Values (which comes in the form of an Arraylist) from a previous page using "PostBackUrl" method.
2. Then allow users to select values from a Dropdown list corresponding to each design code they selected on previous page. (the dropdown values here must come from a backend db)
Also, I want to control the number or rows displayed inside the repeater control. It should be equal to the number of "design codes" selected by the user on a previous page.
Here is my code so far ....

Forms Data Controls :: How To Hide/show Columns Based On The Dropdownlist Value
Jul 16, 2010I have an emergency request that I need to sort it out very quickly as I did not notice it early :(.

Forms Data Controls :: Unable To Bind Data To DropDownList In DetailsView
Sep 15, 2010I have a slight issue I awas trying to fix for 2-3 days, but nothing I try works.
The scenario:
DetailsView control in edit mode, I pass parameters to the SqlDataSourceProducts (edit.aspx?id=2) and the data source selects the appropriate data and fills in the DetailsView form.
Except two drop down lists. These two DDLs (DDL2 and DDL3) are dependent on the previous DDL (DDL1) in the DetailsView.
when the selected value of the DDL1 changes, DDL2 and 3 change their lists and get bound to the database.
The problem is: when I edit something from the database, DDL2 and 3 appear empty and when I update any other field and leave these, they get blanked in the database.
My goal is to set the selected value of DDL2 and 3 to the values in the database WHERE ID = QueryStringField="id".
I can go for not binding the data unless the field is changed, but does not sound professional and user friendly.
code:
The SqlDataSource used to select the parameters from the table and populate the DetailsView
