Hi,

which two tiers do you have? What is your target architectute (Presentation layer, Logic layer, DataAccess Layer)?

I think you have to refactor. There are some hints about this (e.g. books from Martin Fowler) but no general task list like 1. do this, 2. do that ... N. Now you have a three tier application.

[newbie] Retrieving values

I have databound controls, from which I'd like to retrieve the value selected by the user.

System.Web.UI.WebControls.DropdownList
System.Web.UI.WebControls.GridView

cmdCreateNewTaskQuery.Parameters.AddWithValue("@sub_category", lstTaskSubCategory.SelectedValue.ToString()); //Dropdownlist

cmdCreateNewTaskQuery.Parameters.AddWithValue("@priority", lstPriority.SelectedValue.ToString()); //Dropdownlist

cmdCreateNewTaskQuery.Parameters.AddWithValue("@product", "1"); 
                //cmdCreateNewTaskQuery.Parameters.AddWithValue("@product", Products.SelectedDataKey.Value.ToString()); //TODO: Currently hard-coded. //Gridview

I also tried converting the values to (Int64) but it is not possible to explicitly convert strings.

(Int64)   lstTaskSubCategory.SelectedValue.ToString

.NET Framework 2.0

Any ideas?

Confused | :confused:

Hi,

do get an int from a string you have to use int.Parse(). (Better you int.TryParse because of the performance). Did you put int-values in the DropDownLists? Then just try to add with mylist.SelectedValue... (if you debug your code, you can watch the type of the selectedValue, this let you know if the type is correct).

Do you mean something like this?

TextBox1.Text = GridView1.SelectedValue.ToString();
       string mystring = GridView1.SelectedValue.ToString();
       Int32 myint = mystring..?

I meant sth like this

int myInt = int.Parse(GridView1.SelectedValue.ToString());

If your SelectedValue is already a string, then you don't need the conversion.

Tooltip Possitioning problems

Hello peeps

I have a problem setting my tooltip spacing on my page, i am using this to get the spacing.

function ShowDivBox(sendingTD, innerMessage)
{
newdiv = document.createElement('div');
newdiv.style.position = "absolute";
newdiv.style.top = 273 + sendingTD.parentNode.parentNode.parentNode.parentNode.parentNode.offsetTop + 20;
newdiv.style.left = sendingTD.parentNode.parentNode.parentNode.parentNode.offsetLeft + 25;
newdiv.style.zIndex = "5000";
newdiv.style.paddingLeft = "10px";
newdiv.style.paddingTop = "10px";
newdiv.innerHTML = innerMessage;
newdiv.id = "divAddWord";
sendingTD.appendChild(newdiv);
}

function RemoveAddWord(sendingTD)
{
if (newdiv)
{
var id = newdiv.id;
var oldDiv = document.getElementById(id);
if (oldDiv)
sendingTD.removeChild(oldDiv);
}
}

but the problem is when i scroll down in the grid view the grid height makes the tooltip display out of site on the bottom of the page, then more i scroll down on the scroll bar the further down it goes is there anyone who could help me with the correct syntax to subtract the scroll height of my code?

Hi,

How to call a C# function from javascript apart from add attribute.
If we can do it with AJAX,callback or Web services means, then i need it in detail about how to implement it

AFAIK you can call only the Static server side methods from your JavaScript using AJAX. For this you need to set the property EnablePageMethods="true" in your <scriptmanager>.

Also the server side function should contain the attribute [WebMethod]

I am not able to get clue about, which kind of application you are working on. If you are developing Window Forms application then you can use SharpDevelop Form Designer[^] for this purpose, Alternatively if you are working on ASP.NET then you have to try some commercial tool kits Smile | :)
