hi ,
i am using gridview for displaying search result.
after getting the result i want to filter the result by selecting the value from dropdown list which is at the top of gridview.and one more thing when i am selecting any value from dropdownlist the search result should get changed according to selection without going back to the code behind...
how can do that?

Doing this on the client browser would mean using javascript to show and hide the grid rows which is not very easy. Since you are using gridview you cannot get a row id on the client script for each row.
I would suggest you use AJAX to accomplish this. Put the grid inside an update panel and place a dropdown in the header and do the filtering from the serverside using AJAX. I'm not an AJAX expert so you have to dig up the details.

Find out the dropdown in the header row of the grid view and filter the dataview based on the selected value of the dropdown

Take the color in the form of string format and change it into color format..!
You mean to say caonverting text to color i think
if yes follow the below code
System.Drawing.ColorConverter colConvert = new ColorConverter();
lblSample.BackColor = (System.Drawing.Color)colConvert.ConvertFromString("Your Color");
If No
please eloborate..!

I'm not sure if I understand the question right, but based on what I understand, you wish to set the back color for checkboxes that are checked to say "Blue" and the unchecked check boxes are to be left as is. You also wish to persist the details on which check boxes are checked and which are not and if and when needed want to recreate the checkboxes with the same status. Am I correct?
If yes, then
1. To set the color of checkboxes - set the back color of the check box oncheckedchange event. Wire-up all the checkboxes to the same event and use the event source to identify the checkbox
2. To persist the state - there are many way how you can save the state, if the no of checkboxes is a constant and less than 5 you can have individual binary columns in db and save the status directly. If otherwise, I prefer form a Binary string of 1s and 0s representing the state of the checkboxes and then convert it to integer and would store it in the DB. When it is time to re-create the checkboxes, retrieve the int value, convert it to binary and use it to set the status. Remember to persist the number of checkboxes along with the status integer. This is just my way and there may be many different and efficient ways to do the same.

Did you tried to debug your code by putting breakpoint ? What is vlaue of cmd after execution of that line ?
cmd = new SqlCommand("insert into TDept values('" + TXT_TDName.Text + "')", con);
Why you are opening Connection after initilizing the Cmd ?

Hi guyzz.. Im developing a web application here i get datas from the user and on a button click these datas get stored in my data base now i have another button on clicking it,it retrieves all the data from the database and gets saved in my system as an XML file... the code is as follows for the button that creates an xml file...
private void Button1_Click(object sender, System.EventArgs e)
{
SqlDataAdapter da = null;
try
{
con = new SqlConnection();
con.ConnectionString = ConfigurationSettings.AppSettings["DSN"];
da = new SqlDataAdapter("select * from card_details",con);
DataSet ds = new DataSet();
da.Fill(ds,"card_details");
ds.WriteXml("D:\ADIB\OutputXML.xml");
}
catch(SqlException ex)
{
throw new System.Exception ("Error -- " +ex.Message);
}
catch(Exception exp)
{
throw new System.Exception ("Error -- " +exp.Message);
}
finally
{
con.Close();
da.Dispose();
}
}
Now my issue is i need my application to create the xml file,before saving it into my system it should ask me whether to open the file or save the file so that i can specify the file name (something similar to a download window in our web browser)... please advice me...
Thanx in advance..
Regards,
Tash

SqlDataAdapter da = null;
try
{
con = new SqlConnection();
con.ConnectionString = ConfigurationSettings.AppSettings["DSN"];

ds.WriteXml(ss.FileName);
}

Following code should solve your problem:
Response.Clear();
Response.ContentType = "text/plain";
Response.WriteFile("D:\\ADIB\\OutputXML.xml");
Response.Flush();

I wrote my code in VS 2008. Under dialog section of toolbox you can get the specified control.
TRY this Code
System.Windows.Forms.SaveFileDialog saveFileDialog = new System.Windows.Forms.SaveFileDialog();
saveFileDialog.Filter = "XML Files (*.xml)|*.*";
if (saveFileDialog.ShowDialog(this) == DialogResult.OK)
{
string FileName = saveFileDialog.FileName;
if (FileName.Trim() != "")
{
}
}

I did as u said.. but got an error in this line --->
if (saveFileDialog.ShowDialog(this) == DialogResult.OK)
The error stated was --->
<br />
The best overloaded method match for 'System.Windows.Forms.CommonDialog.ShowDialog(System.Windows.Forms.IWin32Window)' has some invalid arguments<br />
Thanx in advance...
