I am using the asp.net mvc framework and like it so far, however there are times that I need to use a code behind page. mainly for my gridview events and such. MVC does not use or recommend using code behind pages. So my question is, how would I put the events for my gridview, or any code that is in my code behine, in my usercontrol and aspx pages?
Would it be as simple as this:
UserControl sample:
<br />
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<ai_dcs_isets.Models.dcs_users>" ><br><br />
<%@ Register Src="PopUpBox.ascx" TagName="PopUpBox" TagPrefix="uc1" ><Br><br />
<uc1:PopUpBox ID="PopUpBox" runat="server" ShowCloseButton="true" /><br><br />
<br />
<script language="C#" runat="server"><br><br />
void page_load(Object sender, EventArgs args)<br><br />
{<br />
<br />
<br />
}<br />
<br />
</script><br />
if so, what is going to keep these events in order if my user control is apart of a page that has it's own page_load or other events? Would my gridview events be a mere copy and paste from code behind to the script area?
Sorry if this is a basic question, web development has never really been my main development.
Thanks for the help.

MVC does not include code-behind for a good reason; asking to use it violates the concepts and principles of the pattern.
What events are you trying to use?

I agree, which is why I need to put what code I was going to use in code behind, in my usercontrol and aspx pages.
The code right now that I need to use:
<br />
void Page_Load(object sender, EventArgs e)<br />
{<br />
<br />
}<br />
<br />
void GridView1_SelectedIndexChanged(object sender, EventArgs e)<br />
{<br />
<br />
}<br />
<br />
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)<br />
{<br />
<br />
}<br />
<br />
And possibly RowCreated event.<br />
Right now it is just this. Some of my code I could move to the Controller and also most can be handled in the Model itself, but events like this I am not sure what to do with.
Thanks for the time.

There is essential no need to handle these events with code-behind, or code-in front
RowCreated is already being done as the view is being rendered
The other events can be handled with JavaScript or by the controller. SelectedIndexChanged I can see being handled with JavaScript.

I understand rowcreated is already being created for me, but there are a few columns that I need to check the value of each time it is created and modify it if needed. RowCreated is generally where this would be done.
I will look for some grid events that can be handled by javascript. I wasn't aware this could be done.
Thanks again for the time and help.

I would evaluate the need for using a GridView control. These [^]links may provide some guidance.

I want to open Pdf file from iframe. i have used this code where i am taking path from my application.
string strOutPutPath = "../MPMA/MPMA Inventory/" + Session["Filename"].ToString() + ".pdf";
ifrm1.Attributes.Add("src", strOutPutPath);
Inside MPMA Inventory all pdf files are there.
Session giving my filename.
But this is perfectally working if i am taking path from my application.

What do you mean not saved in the project? Are you trying to display a PDF from memory? Or is it located at a physical location? If the latter, then get the path and display it.

The files do not have to be in 'my project' but they do have to be in an internet share that have the proper permsissions set.
IIS and aspnet do not have full run of the OS and can not directly access server paths as you mentioned without punching some big holes in security.
So. Create a share, set permissions and you are good to go.

You can use a counter to generate the ids of the textbox. Every time you generate a text box increment the counter by one and store the value back to session or viewstate.
Your code that generates the text box will look something like this.
TextBox newTextBox = new TextBox();
newTextBox.ID = "repeaterTextBox" + Viewstate["COUNTER"].ToString();
At the time of retrieving just loop till the value of counter, you can generate all the ids back, by which you can get the values.

you can try the options provided or need to create dynamic controls at on init of the page.

hello all,
I want to get a value from gridView (grdQuestions) which in turn goes to the textbox which is in another grdView(grdOptions). Now, the problem is how to find the control of textBox(txtText) of "GrdOptions" GridView, so that i can set the "GrdQuestions" griview cells' value into that textbox...
plz help if you understand..
The code is:
foreach (GridViewRow rw in GrdQuestions.Rows)
{
for (int i = 8; i < GrdQuestions.Rows[e.NewEditIndex].Cells.Count; i++)
{
TextBox tb = (TextBox)GrdOptions.Rows[0].Cells[1].FindControl("txtText");
if (GrdQuestions.Rows[rw.RowIndex].Cells[i].Text != string.Empty)
{
tb.Text = GrdQuestions.Rows[rw.RowIndex].Cells[i].Text;
}
}
}

I have textbox in another gridview to which value is to be inserted
But i don't know how transfer that value into that textbox
|
|

do one thing, when you fire the itemcommand on first gridview at that time take that textbox value in some field (such as if many fields then use the datatable ) and give that datatable to the second grid. i.e.
grd2.datasource = dt;
grd2.databind()
protected void grd1_ItemCommand(object sender, GridCommandEventsArgs e)
{
if(e.commandname == "settextboxvalue")
{
string txt1value;
txt1value = (TextBox)grd1.FindControl("txt1").Text;
}
}
in this way you get the value of textbox of first grid now you can assign this to the second.

Please use codeblock/code tags while copying code into the question. That will make it easy to read.
And please also let me know what exception are you getting and if the grdOptions is binded at the time of this operation.

I just want to know how to get the value of one gridview row into the textbox which is in the template field of another gridview .
could you help me in the code?
|
|
|
|
|
(GrdOptions.Rows[0].FindControl("txtText") as TextBox).Text = GrdQuestions.Rows[rw.RowIndex].Cells[i].Text;
I doubt that its not the way which is causing you problem but its the logic.
