I have a query . I want to edit the grid view columns in which user click the edit button he will edit the column in the grid and after that i want to add update button so that when he clicks on updates button after editing the row. The row will be updated and the grid will show you the new update row.
Here is my following piece of code.

AutoGenerateEditButton="true" onrowediting="noticeDetails_RowEditing" >

<ItemTemplate> <%# Eval("CampaignIDRange")%>

Basically grid is about that when user enter values intothe grid, the values will show in to the grid upon click button.I added edit button it works fine but it will incomplete without update button method ...
I have a Gridview where I can modify the Time portion of a DateTime field. The update method is working well, except for one thing:The field should only allow the time portion, e.g 08:23:09 but on the Database it saves it as a full DateTime, e.g 10/18/2010 08:23:09 AM. The problem is that upon editing, instead of adding the existing Date portion, it adds the current Date portion. So if I am editing the item from the last example into 08:25:09 instead of adding it as 10/18/2010 08:25:09 AM it adds it as 10/20/2010 08:25:09 AM which is obviously undesired behavior.Here's how I am doing the update:
protected void grvOutHour_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
GridView grvOutHour = (GridView)this.grvReport.Rows[grvReport.EditIndex].FindControl("grvOutHour");
TextBox txtBox = (TextBox) grvOutHour.Rows[e.RowIndex].FindControl("txtEditOutHour");
[code]...

View 2 RepliesI know that you can call an update on an UpdatePanel server side by calling the Update function on it. I have done this in the past, though in the past I also had a ContentTemplate. In one of my current projects I add all of the controls to a the UpdatePanel in the code behind so there is no ContentTemplate defined. Is there a way to update the UpdatePanel from the code behind despite this, or am I barking up the wrong tree?
<asp:UpdatePanel runat="server" updatemode="Conditional">
<ContentTemplate>
<asp:PlaceHolder runat="server" />
</ContentTemplate>
This is with ASP.NET Web Forms .NET 2.0 - I have a situation that I am not sure how to fulfill all the requirements. I need to update an img source on the page if selections are made from a drop down on the same page. Basically, the drop downs are 'options' for the item. If a selection is made (i.e. color: red) then I would update the img for the product to something like (productID_red.jpeg) IF one exists. The problem is I don't want to do post backs and refresh the page every time a selection is made - especially if I do a check to see if the image exists before I swap out the img src for that product and the file doesn't exist so I just refreshed the entire page for nothing.QUESTION:So I have easily thrown some javascript together that formulates a string of the image file name based on the options selected. My question is, what options do I have to do the following:submit the constructed image name (i.e. productID_red_large.jpg) to some where that will verify the file exists either in C# or if it is even possible in the javascript. I also have to check for different possible file types (i.e. .png, .jpg...etc.).not do a post back and refresh the entire page

I am doing a countdown with a timer that runs every second. I have a scriptmanager, but how do I make it update behind the scenes so the user does not see it? I thought I could use an update panel, but I can't get it to work right.
View 1 RepliesI am trying to use an update panel to run some server sided code. everything works fine with this:
asp Code:
<script runat="server">
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Label1.Text = "Refreshed at " & _
DateTime.Now.ToString()
[Code] ....
The problem is this: when the page first loads, i have a text box that i add a string to. if its a normal string, its fine. but, if its an XML string, the update panel will stop working (no errors, it just wont refresh the panel when the button is pushed). i'v tried narrowing the cause down and found it does not like "<" character.
I tried using this: Server.HtmlEncode to encode the xml but there must be other characters in the string it does not like (the XML is a response from the Linkedin API) .
how i can remedie this? even if the Server.HtmlEncode worked, its not the ideal solution, as i want to display the XML not the decoded string.
how would i do my Gridview delete command like a update command?
im using a datasource... and my delete command is like my update command... so i can change the status into "INACTIVE"...
DeleteCommand="UPDATE ACCOUNT_MAINTENANCE SET am_status = 'INACTIVE' WHERE (accmain_no = @accmain_no)"
UpdateCommand="UPDATE [ACCOUNT_MAINTENANCE] SET [account_type] = UPPER(@account_type), [min_deposit] = @min_deposit, [min_capital] = @min_capital WHERE [accmain_no] = @accmain_no"
when i press my delete command at gridview... the status changed into "INACTIVE" but when i refresh or press f5... it automatically update the status into "INACTIVE" also...

I want MVC pattern to save,update,delete.with detail code
View 3 RepliesI have a detailsview which I am populating using a SQLDATASOURCE, which is bound to a table in a SQL db. Because the number of columns in the table will change, I am using SELECT * from [TABLENAME] to populate the view, this works fine.
My problem is that I need to also be able to update the table and I thought the best way was to generate the updatecommand in the code behind. This is no problem, code is as follows:
[Code]....
But the next stage is to create the relevant parameters for the update command. Does anybody have any thoughts on this? All of the information I have found for the updateParamater reference knowing the final value.
What I really need to do is the code behind equivalent of
<asp:Parameter Name="PARAMETERNAME" Type="Int32" />
Not sure whether this is possible.
