well I don't know about casting, as per previous answer, but you can certainly bind an array to a datatable... clickety[^]

I have a datalist that there is a picture control in it.name of the picture is in database and the picture in a folder on server. how can I change the size of picture that I show in datalist?
|
|
|
|
|
Can you not set the width of the columns of the datalist?
Or once you get the picture you can then convert to image type and edit the dimensions that way.
I think though not 100% sure

hi! guys this is terrible since a while now i've trying to do a very basic data binding, but i'm failing somewhere.let say in my webpage i have a dropdownlist and a textbox(textArea).so the logic is when a user select a text on the dropdownlist(ddCustom by id) its value should be displayed in the textbox.that it.what i've achieved so far is having the dropdownlist text bound but the value is not loading into the textbox field.
here are my codes
<code>
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack)
{
string result = this.validateAll(txtEmail.Text, txtNumbers.Text, txtMessage.Text, txtName.Text, 100);
int resultlen = result.Length;
lblError.Text = resultlen.ToString();
}
else
{
DataSet DsTemplate = new DataSet();
DsTemplate.ReadXml(MapPath(@"~\misc\MessageTemplate.xml"));
ddCustom.DataSource = DsTemplate;
ddCustom.DataTextField = "name";
ddCustom.DataValueField = "text";
ddCustom.DataBind();
}
}
protected void ddCustom_SelectedIndexChanged(object sender, EventArgs e)
{
//txtMessage is the id of the textbox
txtMessage.Text = ddCustom.SelectedItem.value;
}
</code>
sample of the xml file
<?xml version="1.0" encoding="utf-8" ?>
<templates>
<template>
<name>Custom</name>
<text></text>
</template>
<template>
<name>Please call</name>
<text> i'm having a Problem Please call me back at</text>
</template>
<template>
<name>Meeting</name>
<text> the meeting is reported</text>
</template>
<template>
<name>BitrhDay</name>
<text> Happy birth Day</text>
</template>
</templates>
simple isn't it? but don't know.

Add this at the end of Page_Load
ddCustom.Attributes.Add(
"onchange",
"var txtMessage = getElementById('" + txtMessage.ClientID + "');"+
"if(txtMessage)txtMessage.value = this.options[this.selectedIndex].value"
);
This will run on client side.
Your code should also work, but you didn't give us the html from the ASP.NET page.
So... I suppose you did not assign the OnSelectedIndexChanged="ddCustom_SelectedIndexChanged" for your ddCustom <asp:dropdownlist ...="" xmlns:asp="#unknown"> control.

Pretty pretty cool man it's working without any modification.just copy and paste.You are the man!
thanks.
disturbingly simple.By the way why do you select txtMessage.ClientID instead of txtMessage what i would be tempted to do?

Because you didn't tell me enough about your application and I wanted to make the code working with just a copy/paste. 
Seriously now, if your dropdownlist control is placed inside a repeater or it's a part of a user control (or whatever...) , then the ClientID and ID are different.

I would suggest you use an FTP class instead to transfer the file. ASP.NET 2.0+ has it's own FTP classes, and there are others freely available for 1.1 via Google..

Wow, that sounds rather excessive 
You may want to find a way to upload it in 2GB chunks and have the server side repiece those chunks when done. Consider if you are 4.5GB into the upload and something happens, at least you have the chunks there, so you don't have to re-upload the whole file.

Hi,
I want to disply my redirected web page url with query string in status bar instead of address bar. What I have to do? Pls help
Tnx in adv.
Balasubramanian K.

In body tag client side onload event write the following code
window.status = '<%=Request.Url %>';
This will work for you.
|
|
|
|
|
Thank you. It is showing address bar and status bar both. I need in status bar only. What I have to do?
Balasubramanian K.

When you say address bar you mean where someone would type in the name of a website and go to it?
If you do mean this you cant hide the text but you can hide the entire address bar do you want to do that?
|
|
|
|
|
I dont want to hide the total address bar. Why I'am asking is, I am passing user id as query string. For security purpose, I want to hide the query string only or I want to make that the query string should not be changed. At present, I am unable to use Session state. I can use query string only. Thats' why I'm asking like this. Please give me some idea.....
Balasubramanian K.

Why cant you use session state
what you are doing is going the long way around not using session state.
There are some articles out there I think on hiding url variables but I would still recommend session state
