Re: Dropdownlist problem - ASP.NET Discussion Boards

hi,

I have a problem regarding the reset button on my aspx page.

A brief description.

I have aspx page on which over 10 text boxes are there with a save and reset button.

when I have clicked on the reset button it should clear all values in the text boxes.

it is doing the same, but when I click the "Reset" Button second time.

I think I made a mistake on the page load while calling the javascript funtions.

txtCNumber.Attributes.Add("onKeyPress", "javascript:return Integersonly_special(this, event);");
txtMNumber.Attributes.Add("onKeyPress", "javascript:return Integersonly_space(this, event);");
txtFName.Attributes.Add("onKeyPress", "javascript:return Alphabitsonly_space(this, event);");
txtLName.Attributes.Add("onKeyPress", "javascript:return Alphabits_and_nospace(this, event);");
txtEmpId.Attributes.Add("onKeyPress", "javascript:return Alphabits_and_integers(this, event);");
txtRemarks.Attributes.Add("onKeyPress", "javascript:return Remarks(this, event);");

I have doubt using this Attributes concept.

Can any body help me regading this.

your

peter

Hi peter,
There seems to be no problem with Attributes.Add and any ways events are getting fired on KeyPress so if at all they have any problem it will be evident when u enter any value in textboxes.
Are u firing any JavaScript on Reset button ,
Please check if you are doing so,also debug the code on first click of Reset to check what happens .

Your other option is prayer.

There's no fax functionality built in, that's why third party tools exist.

I have a javascript on my page that handels onkey event:

function OnKeyPress(evt)
	{
if(this.GetKey(evt)==13)
		{		    
		    var txtCtrl=this.GetTextBoxCtrl();
		    var sBtnIDtoClick=txtCtrl.getAttribute('btnIDtoClick');
		    if(sBtnIDtoClick != "")
		    {
		        var btnControl = document.getElementById(sBtnIDtoClick);
		        btnControl.click();		        
		    }
		}
return true;
}

This works fine in Internet Explorer 7.0 but not for IE 6.0. (The problem is that the

btnControl.click();

is not fired)

All other JavaSripts works fine, like:

function OnKeyUp(evt)
	{
		var nKey;
		nKey=this.GetKey(evt);
		
		if ((nKey!=38) && (nKey!=40) && (nKey!=13))
		{
			var sNewValue;
			sNewValue=this.GetTextBoxValue();
}
}

Anyone know why?

Thanks
Thomas

Wild guess - it's not supported in IE 6.0.

I have a problem with textbox and dropdownlist.
My form contains ddl's,txt's and some other controls.
On the pageload i am filling dropdown with some list.
While Inserting values into database,
for example,i am using a dropdownlist only for display.If i want to add some data of that dropdownlist kind,i am using textbox.
The requirement is
If i enter some text,it shd check in the dropdownlist.If it has the same value,it should focus on the dropdownlist value,so that user can select it.It will come into the textbox.
This i want when he is trying to add some value(Not on the button click event,keyboard press time.).It should check from the dropdownlist values.

Plese try to understand and solve my little problem.
THanks in advnace.
I am using asp.net 1.1,with sqlsever2000.

Hi,
If I am not wrong you want to check whether the value you are entering in textbox already exist in DropDown ?
Well U can extensively use JavaScript for this purpose,
On KeyPress event of the TextBox
Compare the Value in TextBox with DropDownList options
if it matches any Value of DropDownList using substring method
(ie if Text in the Textbox is found to be the Substring of any existing value of DropDownList Set that option as selected )
This should be the approach according to me.
Give me a Day or 2 iwill try to implement it myself Cool | :cool:

Hi any one help me ,

Towards the success..

Sounds like a lot of work. You'd better get started, or perhaps start looking to buy a library to give you all that.

What is the purpose of DescriptionUrl?
As i have just placed a code:
Image1.ImageUrl = "~/logo.gif"
Image1.DescriptionUrl = "D:\a.html"
Image1.AlternateText = "Logo"
so that a logo appeared with tip as Logo but i did not understand why DescriptionUrl was placed.

Your help is appreciated...........

Hi,

How can I access the datatable in ajax which is returned from a function...

can I have any examples?

Thanks

Sebastian

Hi Sebastian,
Datatable can be used in Ajax ,but it needs to be returned as XML from the Server page ,and then that XML can be parsed and the desired task could be done .
eg: in this code in am converting a DataTable into XML string
(This code is on Ajax Server page which returns XML string to Client page which Implements ajax)

public partial class DataAccessAjax : System.Web.UI.Page
{
  protected void Page_Load(object sender, EventArgs e)
 {
string result;
DataTable  dataTable=GetEmpRecords(); --function returning Dataset  
using (StringWriter sw = new StringWriter()) {
dataTable.WriteXml(sw);
result = sw.ToString();
}
Response.Write(result);
 Response.End();

}

Now XML string is returned of datatable could be used for Ajax implementaion at clientside

Do you mean AJAX, or ASP.NET AJAX, a library for people who don't want to learn how to write AJAX code ? What are you trying to do exactly ?
