Use this code below
cmdsave.Parameters.AddWithValue("@BranchPicture", (branchcontent == null ? DBNull.Value : branchcontent));
Hope this will help.

Why dont you check if file is chosen or not before you do extract file bytes.
There is a property called HasFile which determines if a file is selected.
byte[] branchcontent;
if (FileUpload1.HasFile)
{
FileInfo branchinfo = new FileInfo(FileUpload1.PostedFile.FileName.Trim());
byte[] branchcontent = new byte[branchinfo.Length];
using (FileStream branchstream = branchinfo.OpenRead())
{
branchstream.Read(branchcontent, 0, branchcontent.Length);
branchstream.Close();
}
}
cmdsave.Parameters.AddWithValue("@BranchPicture",branchcontent);
Do like this.

This might not be answer of your question but still I am suggesting because saving whole image in database is no-way a good practice. It will create huge overload on SQL for bringing and saving this much data rapidly.
Instead, you should save those images into one folder in your project and save its relative path like "../images/uploaded/something.jpeg" into varchar field in database. it will save mammoth time while executing.
And while displaying, just bring varchar filed path from database and assign into src field of img

You should probably check for FileUpload1.HasFile before you set the @ContractReminder param and do all that other stuff. Then do a simple if/then using HasFile and set the value of the param to DBNull.Value if there isn't a file.

It's a div with top position absolute.
When you view the source code, check this line:
<div style="visibility: visible; position: absolute; left: 19px; top: 445px; vertical-align: top;" id="myChaser11">
All the controls are put inside the div tag and so they have an absolute position against the page. It will always remain 445px below the top of the page.
..Go Green..

Hi,
I've added some code to my RowDataBound event handler to allow the user to select a row in a GridView. Here's the code:
e.Row.Attributes["onmouseover"] = "this.style.cursor='hand';";
e.Row.Attributes["onmouseout"] = "this.style.textDecoration='none';";
e.Row.Attributes["onclick"] = Page.ClientScript.GetPostBackClientHyperlink(this.MyGridView, "Select$" + e.Row.RowIndex);
Nothing special there, it works fine 
The trouble is, there's a CheckBox control, a templated one, and I need to set it "read-only" rather than disabled as I don't want it greyed out because it doesn't look great.
I know how to access a templated control and I know how to set a CheckBox control to read-only so I tried the following but it didn't work:
((CheckBox)e.Row.FindControl("MyCheckBox")).Attributes.Add("onclick", "return false;");
I think it's because I've already set the "onclick" attributes for the row but I don't know how to get the control attributes set as well as the row.
Any ideas?

hey guys i have a image control in my web form. i want to zoom that image when the user clicks the image.
The image is being retrieved from folder . there are two buttons(Next and Previous) to traverse the images and the information about the image name is retrieved from database.
When the first image loads the zooming works fine. but when i click on next or previous the jQuery for the particular images stops working .
According to what i think is the CssClass is being lost for image control. i have tried mentioning
image1.CssClass="magnify" in every function explicitly but does not work

hi,
This is regarding textbox control, while seeing the page it is showing one value eg: 12/31/1969 but in the view source code of that page shows 12/58/2010.
How can it possible.
|
|
|
|
|
Well, are you looking at the same text control? Are there any other text controls in the page?
The data may be have manipulated by JavaScript code. Is there any JavaScript code that runs on page load?
|
|
|
|
|
Copy "12/31/1969" From your web page. Open the View Soruce, Search >"12/31/1969". Check the result. 
|
|
|
|
|
maybe you are updating the value using a client side code (javascript).

Hi,
I try to manage the absence of students in the exams, try to insert the id of students absent for each matter,to facilitate that to the user i want insert id_student at once (not one after one by textbox simple)is ther any control or method to do that?
Thanks
|
|
|
|
|
Yes, you can take listbox which shows you student id and name (combination, however in background it will give you ids)
so you can select multiple items from listbox.
On each matter, there is two checkbox (absent and present)
so just select multiple student from listbox
and mark absent or present checkbox and insert it
into database.
Hope this will help!

Hi!
How we can paginate a listbox?
Thanks
|
|
|
|
|
You do not required to do pagination in listbox,
it will automatically shows you scroll bar...
The other best option it you do not want to use
listbox is create your custom control.
Because if you are using grid control then it will
not remember your selection when you select
options from multiple pages....
Hope this will help!

Thanks Jinal Desai - LIVE,
creating user control seems complicated,I think using multiline textbox:
the user will simply enter ID of abcent students line and in the end I enter that id in the database by a clic buton ,Waht do you Think?
Thank you.
|
|
|
|
|
ya that will be also nice idea.
If you want to just take IDs then it is fine...

Hi,
That's what I wanted ,it easier for the user but I did not know if there multiline textbox.
I do not know how to check if those id are correct,to prevent the user from making mistakes and insert an id which does not exist in the table student.
Thanks
|
|
|
|
|
Of course there exists multiline textbox in asp.net
You need to use normal textbox and just make it
multiline textbox.
You need to give rows, columns and textmode property according to your
requirement.
Try following....
<asp:TextBox ID="TextBox1" runat="server" Columns="50" Rows="5" TextMode="MultiLine"></asp:TextBox>
Hope this will help!

I want to create a class to persist some data which will be accessible no matter what page I navigate to. I am using Server.Transfer(path, true) to switch between pages, and my first thought was to use a static class. But a static class can only contain static members and I need to instantiate new objects on different pages that need to be accessible from subsequent pages. What is the best way to persist this data in a class? Language is C#, .Net framework 3.5.
|
|
|
|
|
It is very simple.
Just create any class in your web application in .cs file or refer any dll (contains your class)
create instance of it.
Store the object in session or application and you can access it from any of your
subsequent .aspx pages.
Hope this will help!
