Hi
I have a web user control that I create dynamically and then add it to a panel like this:
<br />
MatchingControl control = (MatchingControl)LoadControl("MatchingControl.ascx");<br />
Panel1.Controls.Add(control);
I can deal with the control with no problems before page post back, but when the page is posted back to the server (in response to a button) I can't get the control like this:
<br />
MatchingControl control = (MatchingControl) Panel1.Controls[0];
Any one knows how to do it?
And ever has it been that love knows not its own depth until the hour of separation

The control is gone. You need to recreate it every postback, and you need to create it before page load if you want it to have viewstate.

in your code behind.

Hi,
I have an existing custom control. I have added a new DropDownList control on it. I try to bind the data from to dropdownlist within an overriden CreateChildControls method thats been called on OnInIt event of custom control.
When I try to bind an datatable of <b>my typed data set</B>, it skips out of the CreateChildControls function at on line no. 4 of the following logic
1. director.DataAccess.PopulateDataSet();
2. ddlLocation = new DropDownList();
3. ddlLocation.ID = LocationID;
4. ddlLocation.DataSource = director.DataAccess.DataSet.WO_Location_List;
What might be the reason? Is some thing wrong with the dropdownlist control OR there is some issue with TypedDataset data for that dropdownlist?
Note: This databinding logic works absolutely fine with other dropdownlist controls on a different custom control
Regards,
Vipul Mehta

I think oninit is too early to databind to a control. Why are you doing it so early ?

Hi,
I got this sorted out. Infact the DataType of one field in my select query & the datatable did not matched. As soon as I fixed it out it started working as expected.

Response.Clear();
Response.ContentType = "application/vnd.ms-excel";
string sep = "";
foreach (object column in Columns)
{
string[] value = column.ToString().Split(',');
Response.Write(sep + value[0]);
sep = "\t";
}
Response.Write("\n");
foreach (DataRow dr in dt1.Rows)
{
sep = "";
for (i = 1; i < dt1.Columns.Count; i++)
{
Response.Write(sep + dr[i].ToString());
sep = "\t";

Make a comma the seperator, Excel will hopefully open as a CSV

Create a CSSclass
and then add data with mso-number-format:....
in the css class.
More Info to be found here[^]
We style Date Fields with MSo-Number-Formatting via a static class
public static void styleDataTable(Table table)
{
foreach (TableRow row in table.Rows)
{
foreach (TableCell cell in row.Cells)
{
if (IsDate(cell.Text))
{
cell.CssClass = "tdDate";
cell.Width = Unit.Pixel(80);
}
}
}
}
In the DataTableToExcel Page we place in code behind:
Sesame.styleDataTable(htmlToExport);
(htmlToExport is a created Table based on the datatable)

thanks to both of you, i fixed the style by putting the data into html table and then wrote it in repose object, it was easy 
thanks again

I have to send an email which should have company logo at top of the body and then some texts.
when i'm doing so at the receipent its not displaying any image at all
can anybody give me solution to this question asap......as its urgent
thanking u
Russel

do you understand what email is and how it works ? It's a text only format. Some mail programs can show HTML mail, but the image needs then to be on a public server in order to be visible.
How are you embedding it ?

what is the errormessage?
if(document.getElementById.("dd1_dep_fabric").value=="--Choose Category--")
if this is the exact code you are using, remove . after getElemenById
and ifyou are having the dropdownlist int he content page, it must be prefixed with something like "ctl00_" . use this name in getelementbyid functional call as object name...(check HTML source by right clicking in browser window and select view source....and then look for the name for the control there )
hope it helps

Hi all!
I am indexing Russian text with that code. I have a problem, when I try to search for words in different cases.
Search is productive, only if the word is in the same form, as in the initial (indexing) text. Help me please.
(Whether there can be it because Words in RussianStemmer.cs are stored in the coding KOI8-r?)

Hi ,
I don't know whether it will fulfill your requirement or not, but this is good calendar. And it is in javascript.
Here[^]
Regards
|
|
|
|
|
AJAX toolkit has a calendar extension. You can use that.
|
|
|
|
|
you can create your own control with your specific functionality by extending the AJAX toolkit calendar control...
it is bit easy even for a newbee...
you can even put the checkpoints on date_change event to check for the start date and validating the end date or restricting the selection criteria of end date...
ask help if needed...
cheers !
