Assuming you are running this from a web page, you do not by default have permission to write to the file system, so I suspect that is your problem.

You need to create a datatable and add your data to it, you cannot cast an array to a datatable. If you want to allow nulls in the columns you will have to decalre them as nullable too.

This should get you started

dt = new DataTable();
dt.Columns.Add(new DataColumn("x", typeof(String)));
DataRow dumRow = dt.NewRow();
dumRow[0] = "All";
dt.Rows.Add(dumRow);

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 Smile | :)

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.
I'm from php backgroung.i would do that by an ajax stuff or with jquery.But here i'm surely forgetting something or thinking that asp.net would do everything for me.i search on google, w3school and my codes seems to be ok.need help on this.please let me know as soon as you have time to check this.Thank you!
PS:i'm so frustrated i can't do anything else<code></code>

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. Smile | :)

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..
