Get ClientID If Textbox Name Is In String Variable?
Jun 30, 2010
I have written below code to check for blank value in my textbox but its generating compilation Error.
my code in javascript:
function checkTextboxNotFilled(txtbox) {
var txtb = document.getElementById("<%= " + txtbox + ".ClientID %>");
if (GetFormattedString(txtb.value) == "") {
return true ;
}
else {
return false ;
}
}
error:
'string' does not contain a definition for 'ClientID' and no extension method 'ClientID' accepting a first argument of type 'string' could be found (are you missing a using directive or an assembly reference?)
I am calling it like this : checkTextboxNotFilled("MytextboxName")
I would think that this would work pretty seamlessly, but I am having trouble getting the text from a textBox control in an accordion pane's content to pass into the paypal web payments https post.
If I put an amount in the querystring in my codebehind isntead of passing the text string and click the button in the accordion pane, it works perfectly on the paypal page. But for some reason, I am getting a null return in the text string when I try to make the amount in the querystring whatever the text in the textbox is.
I have tried putting the accordion in an update panel and got the same results....
Am I missing something the get the text from the textbox?
Here is how I am getting the text string in codeBehind:
Protected Sub LinkButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Dim amt As String = donorAmt.Text Response.Redirect("https://www.paypal.com/cgi-bin/webscr?cmd=_donations&business=XXXXXX@XXXXX.org&amount=" & amt & "&no_note=0&item_name=ALT Donor Level Annual Membership&sra=1¬ify_url=http://XXXXX.com/IPN.aspx&no_shipping=0&return=http://www.XXXXXX.com/donate/thanks.aspx&rm=2") End Sub
Note: Some of the paypal string has been removed for privacy
I'm having a problem with <%= obj.ClientID %> expansion, in a .ascx user control.
I have a .js file, containing a javascript function:
function doSomething(objectId) { ... }
I have a .ascx file, with some html elements, and in one element's onclick= I want to call doSomething(), passing the ID of an element in that .ascx file, where the passed ID is of an element other than the one being clicked on, so I can't use "this.".
When I look at the source, I see that the <%=%> substitution has not happened, instead of "doSomething('ctl00_myControl_top');" I get "doSomething('<%=top.ClientID %>');"
For some reason, the script expansion happens in the former case, but not in the latter. The work-around, of course, is not acceptable because it will break if I include multiple copies of the control on a page - only one instance's "redirect()" function will be accessible.
I have a gridview and template field (textbox) control. on GridView_RowDataBound I want to find the control and pass the control id to a javascript which will set datepicker on that textbox here is how I am doing but its not working.
I have a databound gridview that displays basic customer information. I have added a template field to the gridview, but I am having trouble with the coding for the RowDataBound event. I need to take the sum of all payments made by the customer in each row and store it in a variable for further calculation. Also, I need to take an integer value (say 30, representing 30 days) and add it to a date, and return a date.
In asp.net,When I type letter in textbox, textbox doesn't show this letter and save in variable and when i type digit in textbox, textbox shows this digit and store in another variable. How should i do?
