You will need to handle the event in javascript and set the css for the element that paints the node.

Look at the page source and find out how tree-view is getting rendered. Get those elements using JS and set the style property.

Dealing with dynamically created web user control after post back

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.

Problem with Databinding on OnInIt event of custom control

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.

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)

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
