Passing a query string value retrieved to an ImageUrl attribute of an image control using asp.net c#.
I have a page called DisplayImage and within the page_load event i was able to retrieve somevalues from the query stringhcode=Request.Querystring["ccode"].Tostring();
Now,
hcode="6699FD";
How it is possible to assign datatype of an attribute retrieved using sql query to a string? for eg:
SqlCommand cmd = new SqlCommand("select data_type from information_schema.columns where table_schema='dbo' AND table_name=table1 AND column_name=column1, con);
I want to assign this datatype value to a string. How it is possible?
I've basically got 2 applications. One is my back office application (Admin) and the other , the front end application (web site)
My problem is that, the admin uploads 'n' number of photos ,which is stored in one of the folders within my back office application and the path is stored in my DB as , for example : ~/Uploads/test.jpg.
But it is not possible for me to access this image from my front end application because the path actually exists in my back office app. How do i get to view the images that I uploaded on my front end Appn. ?
I have an Image control with the ImageUrl property set to point to an image on a network folder, the address looks like this:
\fs01PRODUCTSimagesAM101.jpg
It renders correctly in IE but not in Firefox.
pasting the url/path directly into the browser, the address is maintained in IE: \fs01PRODUCTSimagesAM101.jpg
But in Firefox, it is converted to this: file://///fs01/PRODUCTS/images/AM101.jpg
I suspect this is related to the problem.
how to pass through a query string parameter of an assignment id and then checking and validating this as a number and displaying the information returned on screen. At present I have code which displays the information on screen but this is by entering in the assignment id and by triggering the button click event, I've shown the code for this below:
.aspx
<div>
<b>Current Assignment</b>
<br />
<asp:TextBox runat="server" ID="txtAssignmentID"></asp:TextBox>
<asp:Button runat="server" Text="Get Assignment" />
<br />
<b>Date Started:</b> <asp:Label runat="server" ID="lblAssignmentStart"></asp:Label>
<br />
<b>Status:</b> <asp:Label runat="server"></asp:Label>
<br />
<b>Current Achievement Level:</b> <asp:Label runat="server" ID="lblAssignmentLevel"></asp:Label>
<br />
<b>Date Last Calculated:</b> <asp:Label runat="server" ID="lblAssignmentCalcDate"></asp:Label>
<br />
</div>
.cs
protected void cmdGetAssignment_Click(object sender, EventArgs e)
{
//Check the assignmentID is an integer
int AssignmentID = 0;
try
{
AssignmentID = TypeConv.CInt(txtAssignmentID.Text);
}
catch
{
}
if (AssignmenttID > 0)
{
//Create new TCAAssignment object by passing the ID
TCA Assignment Current Assignment = abc.TCA Assignment (AssignmentID);
lblAssignmentStart.Text = Current Assignment.dDateCreated.ToString();
lblAssignmentStatus.Text = CurrentAssignment.rTCAAssignmentStatus.dDescription;
if (!CurrentAssignment.dTCAAchievementLevel.IsNull)
{
lblAssignmentLevel.Text = CurrentAssignment.rTCAAchievementLevel.dDescription;
}
lblAssignmentCalcDate.Text = CurrentAssignment.dAchievementDate.ToString();
}
}
Code example passing through a query string parameter of an assignment id would be great.
I have a query string with huge params (greater than 2 KB) and i have to pass it to another page in which there is an email component. I have to send the email with a link (URL) that has the query string so that user can click on the link and access the page.
View 4 RepliesI'm having an aspx page with 2 frames, one is the header and the the other one is content frame which i'm trying to load it dynamically. Everything is fine. Let me explain my scenario
On the header frame i'm having 5 link buttons and when a link button is clicked i'm passing a hardcoded Page URL to the frames containing page and then trying to load that page in the content frame.
Below is my code, Everything as far as i know are in right place, but i cannot see the page in content frame..

Then checking frameURL querystring in default.aspx page load:

when the querystring is null, the SiteSummary.aspx page is getting loaded in content frame without any issue, but when there is a querystring value the page is not being loaded.

Is it possible to specificy height and width dimensions of the ImageUrl attribute in a <asp:HyperLink> control? I tried setting the height and width attributes of the HyperLink control thinking the picture specified in the ImageUrl attribute of the HyperLink control would be resized to the dimensions of the height and width attributes but it wasn't.If I can't somehow resize the specified image for the HyperLink Im gonna have to scrap the control and do it the old fasioned way. By using a regular <asp:Image> control inside an <a href>.

However, when passing a querystring parameter in combination with that url address, the user is denied access.

I'm sure i've got this entirely backwards. However if I change the NULL value in the stored procedure with some string value (eg."Donkeys") it pulls all the values that contain "Donkeys" into the datalist on my results page.

I have an order page done in asp.net c#, and which a user adds ingredients to a set of list boxes, once the user and finished adding items, they get combined to make a sandwich then added to another list box that shows the sandwiches and their ingredients. I also have a button to allow the user to remove the ighlighted sandwich from the order, this all works fine until the page loads up with a query string that skips the adding of ingredients and just shows the sandwiches on a order, the listbox of sandwiches populates fine but I then get an error when the remove button is clicked which is

How do I insert the value of ListID into the query string?
i put this in a grid so that only one of the rows would have the txt box in it, it works ok ie the txtbox only shows up for the row with 1005 as the ID, but for some reason the query string for each row for the last element in the row, ie an AddToCart image button i have at the end of each row in the grid is not coming out right, ie the query string is missing when the page posts back for all but the last row of the grid which coincidently is the row with the 1005 ID, (the rendered code is shown way down, i apologize for the length of it ) here is the problem line. NOTE when i take the code out of the gridview on row data bound event then the page post back fine and the query string is there, but when i put the code back in the row databound event for the grid then the query string vars and values do not get posted back.

My code works fine when running it on my pc, but when I uploading it to the server, I always get the same error, I can't delete file I have just assigned into imageurl.

I am trying to load an image in my webpage from a file server where all of our images will be held.I set the imageurl property on the image control to dynamically;;
image1.ImageUrl =photo+"//"+image1.jpg;(Here photo is a string that value is: "//server/DBV/Documents/Employee/phot")
and I can see the image perfectly fine in IE.
However, the image does not show in Firefox. In Firefox it is just a blank screen when i am using developer tools that image button is in there but it showing faded in developer tool(firebug).in screen nothing showing only blank.
I have a hyper link control and I set the NavigateURL and the ImageURL property at runtime. I also need to set the class of the image tag that it generates but I cannot figure out how I can do that. The solution mentioned here [URL] does not work because the image url is hard coded.
