I am having a gridview control and in the edit template of the gridview control., inside the edit template I need another grid view control., I am having a bound field in the second gridview which always binds to the selected value in the gridview 1 .,
So can somebody tell me in which event and all i have to do the databind for the gridview 2. I am having an sqldatasource for the gridview2.
I have a list view with a label that shows "Step #x", another label with the instructions, and then 2 linkbuttons for editing or deleting. At the footer of the ListView is another button "Add New Step" which opens up an empty TextBox and two buttons to save and cancel. I would also like it to increment the label, but I can seem to find the control in the code behind to change it's text. How do I do this?
Here's the asp markup:
<asp:ListView ID="lvSteps" runat="server" DataSourceID="ldsProcessStep" DataKeyNames="ID" InsertItemPosition="None">
<LayoutTemplate>
<div><asp:PlaceHolder ID="itemPlaceholder" runat="server" /></div>
[Code].....
I'm trying to have an asp.net custom control with a field like:
<ErrorTemplate>
<h1>Error</h1>
<p>Blue wizard shot the food</p>
</ErrorTemplate>
What I want to end up with is:
<h1>Error</h1><p>Blue wizard shot the food</p> in a string in my codebehind.
At the moment, the process I use to get this data out of the template is:
First this gets instantiated into a placeholder by my code:
ErrorTemplate.InstantiateIn(errorPHolder);
which is an asp.net placeholder control - it has to be instantiated into something which can support controls.
What I then want to do is add this to my page using JQuery and a variable, like this:
string script = "var Errortemplate = " + errorPHolder.ToString() + ";";
scriptmanager.register(script); // pseudocode
so the result would be, on my page:
var Errortemplate = '<h1>Error</h1><p>Blue wizard shot the food</p>';
Then I can use JQuery to do someDiv.html(Errortemplate);
Finally resulting in whatever they put in <ErrorTemplate> appearing on the page
Because I'm using JQuery it might be possible to do this a different way, such as adding the placeholder to the page into a hidden div and using JQuery to copy the values out.
I have a gridview with item template and I want the text in that item template label to come from a method in a code behind.
Here is my gridview:

[Code]....
I want to call this method but I'm getting the errors: "
"The best overloaded method match for 'employeepayment.RegTime(string)' has some invalid arguments"
"Argument '1': cannot convert from 'object' to 'string'"
Someone know the answer?. I thought I was right to use Eval.
Im using agrid view which does not using sql datasource and im trying ro Update it this is the Code:
public partial class senior_MarksApproval : PageDataAccess
{
protected void Page_Load(object sender, EventArgs e)
{
Title = "View Marks Approval Requests";
if (IsPostBack)
{
DataTable Ds = DA.getSemester();
lblsem.Text = Ds.Rows[0]["SemID"].ToString();
BindGrid();
}
}
void BindGrid()
{
DataTable DT = DA.GetMarksReqApproval(Convert.ToInt32(DropDownList1.SelectedValue), Convert.ToString(DropDownList2.SelectedValue));
GridView1.DataSource = DT;
GridView1.DataBind();
}
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
String CID = GridView1.DataKeys[e.RowIndex][0].ToString();
String STDNo = GridView1.DataKeys[e.RowIndex][1].ToString();
String Mark = ((TextBox)GridView1.Rows[e.RowIndex].Cells[2].Controls[0]).Text;
DA.EditMarks(CID, STDNo, Convert.ToInt32(Mark), DateTime.Now.ToString());
GridView1.EditIndex = -1;
BindGrid();
}
I want To update Mark and i convert it to template Field ,When I press Update I get the Old value not the Newest One of The Mark and nothing were Updated Except The Date Value in each DataBase and Grid
i use this code for show and converting date in my grid view
<asp:TemplateField ItemStyle-Width = "100px" HeaderText = "DATE" >
<ItemTemplate >
<%# System.Convert.ToDateTime(miladitoshamsi(Eval("Date")))
</ItemTemplate>
</asp:TemplateField>
here show my date and time from data base i learn in below threads how i can bind date from data base that just show date.URL....with this code
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField DataField="Item" />
<asp:TemplateField>
<ItemTemplate>
[code]...
now how i can mix these two code together that convert date from database and just show date?
not quit sure where I've go wrong with this but hopefully someone might have an idea why this isn't working:
This what I thought would work:
[code]....
But it's not! what I get for the OnClientClick attribute is: "DeleteRowKey=<%# dataBinder.Eval(Container.dataItem, "idx_mstrWord") %> "
I've tried several variations (EVAL, BIND, specifying the container and not specifying the container),
none of which gives the expected results; OnClientClick="DeleteKeyRow=12345"
If I add a label and set the text to: <%# dataBinder.Eval(Container.dataItem, "idx_mstrWord") %> I get a number which is what I should but if I try to get it to embed it so my cleint script can work with the data all I get is binding command.
What am I doing wrong? I really don't want to have to kludge around with some hidden field and then have to search through the grid to get at this data key. I need this key on the client side in order to provide additional details in my confirmation popup modal.
I am calling an AJAX Enabled WCF Service from jscript code and I'd like to bind the results to a very simple template. I get the results by calling the service via its jscript proxy:

In the OnComplete function the DataView is created:

The template which the data is bound to is really simple.

I am working on a small application and am using the regular web app template (w/ master page) that comes with webdev express 10. There are four pages on the site, and each of them seems to be working like I would expect. The problem is that the asp:menu that is being used for navigation (part of the template) causes the entire page to redraw every time I use it and it pretty much looks like ass. What can I do to prevent this? I have already tried putting those elements in an update panel, but that isn't working for me. I'm not getting any errors, but it could be a syntax thing.

Template field is not working in 4.0?
I'm trying to bind a List<String> to a DropDownList in a user control. I think I'm doing the right thing, but it seems that after my code executes the bindings are cleared. Here's the code for review!
User control:
<asp:DropDownList ID="subjectNameDropDown" runat="server"/>
<asp:DropDownList ID="yearLevelDropDown" runat="server"/>
Auto-generated designed code-behind:
public partial class NewSiteMetadataUserControl {
protected global::System.Web.UI.WebControls.DropDownList subjectNameDropDown;
protected global::System.Web.UI.WebControls.DropDownList yearLevelDropDown;
}
Code-behind:
public partial class NewSiteMetadataUserControl : UserControl
{
protected override void CreateChildControls()
{
subjectNameDropDown = new DropDownList();
yearLevelDropDown = new DropDownList();
}
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
EnsureChildControls();
// Attempt 1
List<String> subjectNames = GetSubjectValues();
foreach (var subjectName in subjectNames)
subjectNameDropDown.Items.Add(subjectName);
subjectNameDropDown.DataBind();
// Attempt 2
List<String> yearLevels = GetYearLevelValues();
yearLevelDropDown.DataSource = yearLevels;
yearLevelDropDown.DataBind();
}
}
Should this approach work? If it should, how can I debug what happens after the code executes?
how to get hidden column value in gridview in asp.net
View 3 RepliesI am currently building a system that allows the administrator of our website to update the RSS feed by adding new items, editing current ones and deleting old ones. I have put all of the fields into a template view, because this way, they provide the functionability that I need.
Anyway, because the bodies of the RSS feed will be quite large, I want to be able to have a link in a column, which sends the admin to a page called NewsDetails.aspx?<guid>. <guid> here means the ID tag that I have named 'guid'. When I hover over the link, the correct url appears in the status bar (i.e. www.mywebsite.com/admin/NewsDetails.aspx?1), but when I click on the hyperlinks, they don't navigate to the page, but simply refresh the current page.
