Hi I am trying to use a textarea control to load some text into. I am then asking the user to update the text and then finally save it to a file. The problem is that the text saved is always the loaded text and not the text updated by the user....
Load code
TextReader tr = new StreamReader(textpath);
textarea1.Value = tr.ReadToEnd();
tr.Close();
Save code
string fullpath = string.Format("{0}RichTextFile{1}.doc", tempfile, dateTime.Now.ToFileTime().ToString());
string htmltext = textarea1.Value;
htmltext = htmltext.Replace("<STRONG>", "<B>");
htmltext = htmltext.Replace("</STRONG>", "</B>");
htmltext = htmltext.Replace("<EM>", "<I>");
htmltext = htmltext.Replace("</EM>", "</I>");
StreamWriter sw = new StreamWriter(fullpath);
sw.Write(htmltext);
sw.WriteLine("</html>");
sw.Close();
Any idea why it is not saving the updated text?

Hi,
You will need to ensure that the code to populate the TextArea is not being fired on PostBack. If it is then the control is updated with the old value prior to the button event firing i.e.
<br />
if (!IsPostBack)<br />
{<br />
TextReader tr = new StreamReader(textpath);<br />
textarea1.Value = tr.ReadToEnd();<br />
tr.Close();<br />
}<br />
This will ensure your code is only run once when the page first loads.
Hope this helps...

Hi !
you can do something like this.
DataSet ds=new DataSet() ;<br />
try<br />
{<br />
SqlDataAdapter adapter; <br />
cmd.Connection.Open(); <br />
adapter = new SqlDataAdapter(cmd); <br />
adapter.Fill(ds);<br />
cmd.Dispose();<br />
adapter.Dispose();<br />
return ds;<br />
}<br />
catch<br />
{<br />
cmd.Connection.Close();<br />
}<br />

Hope this will help you to solve the problem.

There is no inbuilt control available. Use third party programs like FCKEditor or TinyMCE.

Have you thought of using JavaScript and not using the UpdatePanel control at all? From experience the UpdatePanel is not a great control and if all you are looking to do is toggle the display of a block-level element, then the following would be far easier in my opinion:
Your JavaScript...
<br />
function toggleDisplay(toggleDiv)<br />
{<br />
toggleDiv = document.getElementById(toggleDiv);<br />
<br />
if (toggleDiv.style.display != 'none')<br />
toggleDiv.style.display = 'none';<br />
else<br />
toggleDiv.style.display = 'block';<br />
}<br />
Your HTML...
<br />
<asp:Button OnClientClick="toggleDisplay('toggleDiv'); return false;" ID="btn_search_by_area1" runat="server" Text="Search Sub Dep." /><br />
<div id="toggleDiv"><br />
ghjgjhgg<br />
</div><br />

this can be done using script.
use the script function below..
function FindPrice(ctlCurrentPrice,txtDiscount,ctlCustomerPrice)
{
ctlCustomerPrice.innerText = Number(ctlCurrentPrice.innerText)-
Number(ctlCurrentPrice.innerText)*Number(txtDiscount.value)/100);
}
and use the following code inside the RowDataBound event of gridview..
if (e.Row.RowType == DataControlRowType.DataRow)
{
TextBox txtDiscount = e.Row.FindControl("txtDiscount") as TextBox;
txtDiscount.Attributes.Add("onchange", "FindPrice(" + e.Row.Cells[0].ClientID + ",this," + e.Row.Cells[2].ClientID + ")");
}

1. I have the following tables in the sql server
(a) tblforms - This table contains all the form names of the project
(b) tbluserdetails - This table contains the user information
(c) userforminfo - this table contains the information about which form pertains to which user.
2. I have a web form named form management , there in the form , i have the dropdownlist and a gridview.
in the gridview , i have two columns (formname , checkbox)
Dropdownlist populates all the user names , and the currently selected user name in the dropdownlist selects the form name in the checkbox of gridview .
Now my question is , how should i select the form name for the particular user and leave the rest unselected in the checkbox.
According to my understanding , i should first populate all the formnames and then for the currently selected user in the dropdownlist , i should extract all the formnames for that user.Now for each form name(extracted for the user) i should loop for 25 forms (because i have 25 forms i the gridview).
Am I proceeding in the right direction ?

Best method would be to bind all the forms from "tblforms" table to the grid view. In grid view's RowDataBound event, query "tbluserdetails" table to find user has this form. If yes find the checkbox and check it.
|
|
|
|
|
i have another question.
The administrator is assigning the forms authorization to the user by clicking the checkbox parallel to the forms .
Now , I am going to tell you , the process of assigning the authorization to the user , which i implemented.
I select the form name which ever i have to assign to the user , then i click the save button , now lets say the user select ten forms, then i am iterating the gridview records , i mean putting each record into the loop , now the selected record will go into the database , the rest will be deleted.I mean if i have 25 forms , then iteration will take place 25 times.
Each record is being saved one by one in the loop.
Am i doing right ?

Yes it looks like. Alternatively you can create all insert statements and do a supply all at once which will be much faster as you are opening the connection only once.
|
|
|
|
|
in the user authorization table , there exists following fields
auto increment id
user id
formid
during the insertion the user id being fetched from dropdownlist
and the formod form the gridview
can u please elaborate the method u mentioned latter.

U mean SQL Bulk Copy ?
If it is that , then i need to create a teporary table which will have the userid and formid field.
because the user id lies in the dropdownlist and the formid lies in the gridview.
