if you are Binding GridView with SqlDataSource then use FilterExpression of SqlDataSource then bind again GridView
example:
SqlDataSource1.FilterExpression = "ColName ='"+getSelectedItemofDropDownList+"'";<br />
GridView1.DataBind();
I Love SQL

here is a sample code similar to your situation-- loading cities in dropdown inside gridview based on the state selected from the dropdown outside the gridview. this link will provide you atleast something useful. Have a look...

--call "subInitializeDropDown" on PageLoad
Private Sub subInitializeDropDown()<br />
Dim LocalDataSet as New DataSet<br />
LocalDataSet = SelectAllProducts()<br />
ddlProduct.DataValueField = "Product_ID"<br />
ddlProduct.DataTextField = "product_Name"<br />

Hi All,
i am working on a web application which saves html file(file consist only formatted text with color, headings, font etc.). i need to write this formatted text to a word file(on click of a button). i am doing it like this:-
// on click of button, i call this function.
private void write()
{
object oMissing = System.Reflection.Missing.Value;
//Start Word and create a new document
Word._Application oWord; // word application object
Word._Document oDoc; // word document object
oWord = new Word.Application();
oWord.Visible = true;
// open new word file
oDoc = oWord.Documents.Add(ref oMissing, ref oMissing,
ref oMissing, ref oMissing);
//Insert a paragraph at the beginning of the document.
Word.Paragraph oPara1;
oPara1 = oDoc.Content.Paragraphs.Add(ref oMissing);
// call a method setContent(), which will return string
(here string will contain html file content(text) like:-
<code><div class="ForumSig"><b>here all my formatted text will go, it can be any number of paragraphs with any type of formatting, but will have text only</b><u><b>CodeProject<b></u></div></code>
)
string tcontent = setContent();
oPara1.Range.Text = tcontent;
// write returned html content(string) to opened word file.
oPara1.Range.InsertParagraphAfter();
}
this is simply what i am doing, this opens a new word file and writes all what my function "setContent()" returns (a string representing html file content).
now problem is that it is writing that string as it is means if string is <code>

An easy solution would be changing the HTML extension to .doc and save. This works for me.

Yes Navaneeth this will work for some situation, in my case i am using a third party tool for text editing. user can enter any text on that tool(supports formatting through it's own options on tool) and click on on save button, then i need to save the content in database, those content will be like having color , fond, and some other properties for faormatting the text(including text too).
this tool has one prorerty named as "content", i can only access user entered text with this property "content", which always holds string of all above proerties(like font etc with user entered text) which i just reffered.
when i will take this string and save to database it will saved as it is(proerties + text). when i open a word document and assign this string(which i will retirieve from database in a string) to a paragraph and will write to word, it will take whole string and write it as it is like if html content was <b>"People"</b> it will write <b>People often</b> into the word, not like just making "People" as bold(i mean it will ignore all html tags and consider those as normal set of characters only and will write tags too).
so i think it is something different from the condition for which this suggestion might have work for you.
if i am wrong please let me know...

You can't. The best you can do is to save the html files it generates, and then modify them so that all the links on them link directly to other html files you have created. No postback is going to occur, how successful this can be would depend entirely on how static your site is. If it has a forum, for example, forget it.
