View 3 Repliesthe problem is actually in the subject. I have custom control that uses treeview. The control is added dynamically. Nodes for this treeview are populated on demand. Treeview nodes can be checked. I recreate this control on page load event, but still CheckedNodes is empty if checked nodes were added dynamically (added on demand).

View 1 RepliesHow can i check a parameter value and add onto or remove conditions from my where statement.Here is what i mean.. i have a stored procedure that is being used for returning small set of fields based on a parameter that it is expecting. Since the only difference between the select statements are the last AND condition, i was wondering if i can check that parameter as im doing now but change that AND condition so that i have only 1 select statement instead of 3 within my procedure.Current Example:
if @rptNum = 1
begin
Select * FROM tblName
[code]...

View 3 RepliesI just read this:
http://www.albahari.com/nutshell/predicatebuilder.aspx
I have a couple questions,
1. is that predicateBuilder the only way to do this?
2. will the following code produce 'AND' or 'OR' connecting these?
foreach (string sParam in sParams)
{
query = query.where(item => item.Whatever == sParam);
}
assume query is an IQueryable<t>. This stucture also dynamically builds the where predicate right?

View 2 RepliesI have problems building a GridView programmatically. My code is:
[Code]....
This displays the GridView with the following problems:
1. The Html constructed in the Subject column displays on the page as raw Html. The source code shows the Html characters in their ASCII form. The function HTMLEncodeSpecialCharacters is obviously incorrect.
2. The PagerSettings display the page numbers only (1 2 3 4) and not the First and Last text (want to display << 1 2 3 4 >>) despite setting PagerSettings.Mode = PagerButtons.NumericFirstLast.
3. Clicking the page numbers is always one page behind. For example, when the page is opened, page 1 displays. If I click 2, page 1 still displays. Then click 3, page 2 now displays. Click page 4, 3 displays. Click 2, 4 displays etc etc.
4. The column headings are aligned in the centre despite setting HeaderStyle.HorizontalAlign = HorizontalAlign.Left.
i wnt to creat a EDITABLE GRIDVIEW , in code behind ( not using sql data source or anything ) want everything happen in code behind using C#

View 1 RepliesI have a pretty simple C # page that when the page first loads, a bio is diplayed in that center section based upon sql executed from my code behind. I have 4 link buttons on the page that when clicked, fill that center section with other content based upon which link button they clicked (News, Publications, Contact Info, and Presentations). I was all done, then I thought about using an UpdatePanel to get rid of the annoying "flicker" when the page posts back on the click of the link button.

I have gridview that I am filling with records from SQL database. However, I want to populate the gridview with records that match text search criteria. In other words, I want to be able to key in a word like "network" in a text box, pick up the text, read records and pick up on the records that match that criteria. I am doing fine with building the gridview but I am a bit new to this and I don't know what I do to do text search.

the design of my page because of the treeview menu. I am using a treeview for the purpose of issuing accessibility of users regardless of their position. Actually, the treeview menu control overlay the footer whenever I expand on it. How am I be able to dynamically adjust the height of the <div> for the treeview menu.
View 1 RepliesIs there a better, cleaner way to do this in ASP.NET 2.0?
An ASP.NET 2.0 page displays a datalist of records. Each record can have many dates, so the dates are in a nested gridview (I chose a gridview over a datalist here because we want to be able to delete a date and this is easier done in a gridview). The parent record can never be deleted.
The display works fine: the nested gridview gets its datasource during the parent datalist's OnItemDataBound event.
The problem: the nested gridview's delete function. The date gets deleted without a problem (handled in the OnRowDeleting event), but somehow the redisplay is untying all the other nested gridviews from their datasources. The delete does not appear to cause a page postback, so I don't know how the other nested gridviews are losing their datasources.

how to do it using c# all data child come frm data base
I have some data which contains angle brackets in some of the fields.Even if properly escaped as <: or > (or even the hex codes), or contained in CDATA, in Visual Studio 2005 ASP.Net, the field data is being truncated at the first angle bracket. If I replace the data with curly braces, it displays fine.Is this a parser defect in the TreeView control? I can use Response.Write and see that the data provided by the XmlDataSource is fine. Example:
<ITReview>
<row TopNode="REQ 123456 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/><row TopNode="REQ 456789 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/>
</ITReview>
<ITReview>
<row TopNode="REQ 123456 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/><row TopNode="REQ 456789 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/>
</ITReview>
This truncates right after TT Description. If I change to curly braces or parentheses, it displays fine.
