View 2 RepliesCan i put gridview inside gridview and bind data to that inside grid?
View 4 RepliesI've got a fileupload control inside of a gridview so that each row (item from the database) can have an attachment associated with it. I've got a button next to the fileupload control (besides the default browse... button to select the file) to actually take the file and upload it to a file server. This works great if I use this button "Upload". However, underneath my gridview I have another imagebutton that is outside of the gridview, its just sitting on the form / page. The idea of this "Update" button is when end users make changes to the grid I can simply loop through the grid and update the values they have entered to the database. This also works great.
Now here is my issue assume a user has 3 rows in the grid view. On 2 of these rows he decides to add an attachment but he never clicks the "Upload" button he only uses the standard browse button to select the file. Now instead of clicking the "Upload" button that is on the grid view he ends up clicking the "Update" button outside of the grid thinking that it will save his attachments. So I decided to write code to grab the fileupload control from the grid using .FindControls("NameOfFileUploadControl") in my Update button loop where I loop through all the rows. Then I check if myFileUploadControl.HasFile property to see if there exists a file and if there does upload the file then continue with the code.
The issue is when I click this "Update" button .HasFile always returns false even though I can see the text string of the path in the fileuploadcontrol textbox (the standard one next to the browse button). Is it because this goes back to the page load event and checks if it is a post back? What causes this and how can I fix it? Im adding some code because im still confused with this
Protected Sub SaveGrid()
For Each Row As GridViewRow In Me.gvLineItems.Rows
Dim f As FileUpload = CType(Row.FindControl("fuAttachment"), FileUpload)
'todo: this part is not working
If f.FileName.Length > 0 Then 'returns 0 always
'this returns 0.
end if
if f.HasFile() then
'this also returns false
end if
Next
End Sub
This method gets called on a click of a button. The fileupload control is in an of a gridview that is wrapped inside of an UpdatePanel:
<asp:FileUpload Width="90px" Font-Size="xx-small" ID="fuAttachment" runat="server" />
I have an UpdatePanel with a GridView. This GridView has a template column that is a DropDownList. The problem is that the SelectedIndexChanged event does not fire for the DropDownList. Here is the code:

I have a gridview with edit field. It has a footer row for insertion functionality. Now i also have a fileupload control in footer for uploading files on server. The url of files are stored in sql server2005. Now i have a fileupload control in <edititemtemplate> of gridview which can be used for uploading files while updating of gridview.
Now my req is whenever i upload file with fileupload control in <edititemtemplate> it should update the url of corresponding file in sqlserver2005. My query for update in sqldatasource is-
[Code]....
Here draw_url is url field for my uploaded files.
How can i achieve the above functionality
I've been looking around and trying a lot of different tactics to solve this issue but basically the senario is this.I have a gridview with a fileUpload in it.I can upload a file perfectly and it writes to the database.The trouble starts when I update a different cell and don't touch the cell with the fileUpload in it,it'll postback a null value to the database.
How can I keep the fileUpload control from sending a null on postback to the database so it won't clear out my entry if there isn't a new one to replace it?Or alternatively,how to I default the value to the old value on postback if nothing was entered through the FileUPload control?

I have four controls in my page: FileUpload, LinkButton, GridView, and Button.
FileUpload - I use the control to browse and open an Excel file in the client machine.
LinkButton - I use the control to trigger the method that copies the Excel file to the server, converts the data of Excel file to DataTable, deletes the Excel file, and returns the DataTable.
GridView - I use the control to display the data.
Button - I use the control to save the data to the database.
I did not see any problem until I uploaded the third file that hanged my page. I noticed that every time I upload a file, the page become slower gradually.
Each Excel file has 2,000 records, and every time the GridView displays an item, it searches the data on the database. I think, the more the data in the database, the slower the searches can be.
I set the AllowPaging property of GridView to true. The less displaying of items, the less searching of data can be. But, every time I change the page of GridView, I have to bind again the data to the GridView. In order to bind the data, FileUpload must contain the source file, but not because FileUpload frees the file when the page posts back. And I don't want the user browses the file every time he changes the page of GridView.
I have something like this:

This does NOT work. What's wrong here?How do I accomplish my goal? I MUST use the Button1_Click event for this one.
I have gridview in my page that users can edit their data in gridview... and in this gridview I define label that I want when users click on Edit button it change label3.text:
below is code:
<asp:GridView ID="GridView1" runat="server" CssClass="DGridView1"
AutoGenerateColumns = "false" Font-Names = "Tahoma"
Font-Size = "9pt"
HeaderStyle-BackColor = "#e0e0e0"
OnPageIndexChanging = "OnPaging" onrowediting="EditCustomer"
onrowupdating="UpdateCustomer" onrowcancelingedit="CancelEdit"
GridLines = "Both" OnRowDataBound = "OnRowDataBound"
>
And .cs:
protected void EditCustomer(object sender, GridViewEditEventArgs e) {
Label Label3 = (Label)GridView1.Rows[e.NewEditIndex].FindControl("Label3");
Label3.Text = "neda";
GridView1.EditIndex = e.NewEditIndex;
BindData();
BindData1();
}
but here when I click on EditCustomer it doen't change label3.text
I use a tabcontrol with 2 tabs. In the second tabpanel as seen in the code I use a Fileuploadcontrol to upload Images from a users computer.
The problem is that I need to surround the tabcontrol with an updatepanel as I dont want a fullpage postback when switching between these 2 tabpanels. In this code I have the tabcontrol inside an updatepanel but the problem is that the Fileupload controls does not seem to work inside an updatepanel.
How will I solve this problem as I dont want a fullpage postback when switching between the tabs ?

I want to use an asp fileupload inside a updated panel, but each time i upload something it say please upload file ....
View 1 RepliesI have a Listview that houses a FileUpload control. However, after using findcontrol the next line of code tries to convert the filename into a string and produces the familar error object reference not found.
Note: I have used identical code in a formview and it works fine.
Here's my relevent codebehind:
protected void AccessDataSource1_Inserting(object sender, SqlDataSourceCommandEventArgs e)
{
FileUpload FileUpload1 = (FileUpload)ListView1.FindControl("FileUpload1");
string Fupload = FileUpload1.FileName.ToString();
DateTime DateNow = DateTime.Now;
string DateNowSTR = DateNow.ToString();
string NewImageName = DateNowSTR + Fupload;
FileUpload1.SaveAs(Server.MapPath("~//images//" + NewImageName));
e.Command.Parameters["SponLogo"].Value = NewImageName;
}
Following is my html design
<asp:UpdatePanel ID="up1" runat="server"><ContentTemplate>
<asp:FileUpload ID="FileUpload1" runat="server" />
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="upload" />
<asp:Label ID="Label1" runat="server" Text=""></asp:Label> </ContentTemplate></asp:UpdatePanel>
and
if (FileUpload1.PostedFile !=null) {
//my upload code here....
}
without update panel it works fine.after place all control inside update its not working. How to fix this...
using vb.net/asp.net 2005.I have a control inside a nested gridiview. I am throwing an event for this control where I have the value of the DataKeyName for the gridview but I also need the selectedRow of the nested gridiview.Since I am in the code that is not a rowCommand how can I find the selected gridview row just using the DataKeyName?
View 1 Repliesi want to save the value from textbox that inputted by the user and save it in the database.. the textbox is dynamically populated or depends on the number of questions from the database..

I a using Visual Basic, take this into consideration.
I do have the following GriedView:

ImageUrl='<%# IIF(System.IO.File.Exists(Server.MapPath(string.Format("~/UploadedImagesClassifieds/{0}{1}", Eval("AutoNumber"), "Pic1.jpg"))), string.Format("~/UploadedImagesClassifieds/{0}{1}", Eval("AutoNumber"), "Pic1.jpg"), "~/UploadedImagesClassifieds/NoPicture.gif")
%>'
/>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>
<asp:BoundField DataField="Category" HeaderText="Category" />
<asp:HyperLinkField HeaderText="Listing Title" DataNavigateUrlFormatString="~/Classifieds/DetailPage.aspx?AutoNumber={0}&FlagForm=NoSubmitted" DataNavigateUrlFields="AutoNumber" DataTextField="ItemTitle"/>

<asp:BoundField DataField="EnterDate" HeaderText="Listed on" />
<asp:HyperLinkField HeaderText="See trade history" DataNavigateUrlFormatString='<%# IIF( Eval("UDTIItemDescentFrom").ToString <> "Parent", string.Format("~/Classifieds/SearchPageWithForm.aspx?AutoNumber=", Eval("UDTIItemDescentFrom"),
"&KindOfSearch=ShowMyUDTIGameDownlines"), string.Format("~/Classifieds/SearchPageWithForm.aspx?AutoNumber=", Eval("AutoNumber"), "&KindOfSearch=ShowMyUDTIGameDownlines") ) %>' Text="See trade history"/>
</Columns>
The code inside the PostBackUrl=' and ImageUrl=' are working fine. I tried to do the same, with the code inside the DataNavigateUrlFormatString=' but it is giving me a hard time. It is not working.
