Thank you for answering to all my previous queries. All were very helpful. Now I'm facing another issue.
In my form I'm dynamically generating two dropdownlist controls. One is for country and other is for state. I can able to fire the SelectedIndexchanged event of Country dropdown and getting the id of Selected Index.
However, while selecting the control from Repeater control, eventhough FindControl Method is getting reference, the correponding dropdownlist is getting the null reference. Any idea what's happening?
Following is the code:
DropDownList CountryDropDownList = sender as DropDownList;
string controlName = string.Empty;
string ChkDropDown = CountryDropDownList.ID;
if (ChkDropDown.Contains("Country"))
{
int CountryId = Convert.ToInt32(CountryDropDownList.SelectedValue);
dt1 = Codtls.GetStatesList(CountryId);
foreach (UserField userField in _userFields)
{
if (userField.Name.Contains("State"))
{
string vaulueControlName = String.Concat("UserFieldValue", userField.Id);
controlName = String.Concat("UserField", userField.Id + "_" + userField.Name.ToString().Trim());
Control valueControl = UserFieldRepeater.FindControl(controlName);
DropDownList StateList = valueControl as DropDownList;
StateList.DataSource = dt1;
StateList.DataTextField = "_Statename";
StateList.DataValueField = "_StateId";
StateList.DataBind();
}
I tried to put the line, DropDownList StateList = (DropDownList)valueControl; then it is giving me the error ' Cannot cast repeater item to a dropdownlist'. Anybody can provide any help please?
Thanks in advance.
Success is the good fortune that comes from aspiration, desperation, perspiration and inspiration.

You might have to go old school and get it out of the response.form collection. Or you could set the onkeyup of the textbox to call some script which will write the contents of the textbox into a server hidden control. That you can get from the viewstate.

How can I detect a continous mouse down state? I need to auto-increment a numeric text field as long as the mouse is held down over an up botton and decrement for a down bottom. As soon as the mouse is up, the process stops. I believe I probably need to two frames, when the mouse is pressed, the head moves to the second frame which detects whether the mouse is down. If it is, increment a numeric variable, display the variable, then send the head back to the first frame that repeats the process of the second frame. I can increment the numeric variable and display it but I am not sure how to detect a continous mouse state.

try setting a javascript timer. The timer would start on mousedown and then fire a function to see if the mouse is till down and increment your value.

how to convert awebsite from two tier archtecture to three tier archtecture
|
|
|
|
|
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.
Regards
Sebastian

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());
cmdCreateNewTaskQuery.Parameters.AddWithValue("@priority", lstPriority.SelectedValue.ToString());
cmdCreateNewTaskQuery.Parameters.AddWithValue("@product", "1");
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?

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).
Regards
Sebastian

Do you mean something like this?
TextBox1.Text = GridView1.SelectedValue.ToString();
string mystring = GridView1.SelectedValue.ToString();
Int32 myint = mystring..?
Jon
|
|
|
|
|
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.

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]
