I have followed your Nested level gridview and found it working, but i want add a button in the child element(from your example i will have a btn in Product grid and it should get contact_id (parent datakey value as well) ),as i need to update in database.
I need to get access to the page index of the gridview so I can correctly get some data from a coresponding array to set the cell's contol properties correctly. Below is what I've got so far. The ExcelObject is a class that houses both the data read in from an sutomer submitted excel file and a matching 2 dimensional array of characteristics that I use in this case to set the CssClass property. My problem is that when I enable paging for the gridview I don't get the proper datasource row index when the data is read by the databinder.eval; what I'm getting is the current row of the gridview being generated.
I have a masterpage that contains all the javascript and inside the content control, there is a link that calls a javascript function and I want to pass the id once it's rendered differently by the server.
<asp:TextBox ID="txtstart" runat="server" Width="20%"></asp:TextBox> <a title="Pick Date from Calendar" onclick="calendarPicker('<% txtstart.ClientId %>');" href="javascript:void(0);">
However, I keep getting this error:
Property access must assign to the property or use its value.
I'm dynamically adding a DropDownList to the GridView in edit mode and I have set the TextBox Visibility to False. In edit mode I can see the DropDownList and I'm able to select an Item from the DropDownList but not able to access the SelectedValue in RowUpdating Event. How to get the selectedvalue of this DropDownList?
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound If e.Row.RowType = DataControlRowType.DataRow And (e.Row.RowState And DataControlRowState.Edit) > 0 Then Dim ddl as DropDownList FillStateList(ddl) e.Row.Cells(4).Controls.Add(ddl)
ddl is the DropDownList that is added dynamically. And the default Textbox that is in the Edit mode is set to invisible. So there are actually two controls in the same cell in edit mode(TextBox is invisible).
If I use the above statement I'm getting NullException.This is Probably because its a BoundField. Is there a way I can access the DropDownList 'ddl' SelectedValue?
I currently have a repeater control and inside the itemtemplate I have a usercontrol. This usercontrol renders correctly, but I am trying to assign a dataitem to a property in the repeater control.
[code]...
RequestId is just an Int32. It just doesn't assign it.
I can put the eval outside of the usercontrol just in the itemtemplate and it correctly outputs the right id.
If I remove the whole eval and just type a number in then it works fine. I was using an EntityDataSource and this automatically binded to the repeater. It printed out all the information from the database on the screen without any codebehind. But when I put in the code behind Repeater1.DataBind(); it then started to work.
I don't know why, but hey it's solved. It now successfully passes the value through. I imagine it has something to do with the page lifecycle.
foreach (DataGridViewRow item in dataGridView1.Rows) { if (Convert.ToBoolean( item.Cells[0].Value) == true) { foreach (DataGridViewColumn col in dataGridView1.Columns) { **class oclass=new class(); oclass.property = item.Cells[col.Name].Value.ToString(); Collection.add(oclass);** } } }
In the above syntax,i want to fill class property dynamically.I also add my class in collection.Is it possible in C#,fill class property dynamically?My grid contain more than one column.My grid's column name are same as class property name.I want to do the bellow thing:
foreach (DataGridViewColumn col in dataGridView1.Columns) { **class oclass=new class(); oclass.col.Name= item.Cells[col.Name].Value.ToString(); Collection.add(oclass);** }
I have a user control in asp.net that i need to dynmically set properties for. The propety and property values are in a dictionary, for example:
Dictionary<string, string> propertyValues; Control c = Page.LoadControl("~/Control.ascx")
I can currently set the properties on the control using reflection, however, with .net 4 and the new dynamic keyword, is there an easier way to do it, for example, something like this:
I get this error when I try to have my C# class change the skin of an asp control:
The 'SkinId' property can only be set in or before the Page_PreInit event for static controls. For dynamic controls, set the property before adding it to the Controls collection.
My goal is to provide a panel, call it ID="response", on every page, and then dynamically change it's CSS class from Error to Success, or Success to Error (so it's red or green). And also I make it visible = true, when a response is created.
Apparently, I am forced to use CssClass attribute, which is the only way this will work.
As a side-off-topic note: In PHP, you would not have a problem of using different "pre-init" "post-init" etc. A completely unnecessary process. You would simply change the html before you send it back to the user. I'm a bit confused why ASP.NET decides to overcomplicate everything. It's a bit silly for me to take time to learn all these different complicated processes to simply display a webpage. It takes time to learn all the quirks written in difficult-to-read ASP life-cycle documents on microsoft. Not to insult any microsoft people, but it's just not practical.
How to set proprety for List dynamically. I have a WebPage class having properties. strNodeName is one of the property of this class which is the parameters of method. I want to set the string strTitle according to the parameter strNodeName i.e., set
strTitle = _list[i].Title.ToString(); I want Title to be the strNodeName. Like if strNodeName = Author, then strTitle = _list[i].Author.ToString(); if strNodeName = CoAuthor, then strTitle = _list[i].CoAuthor.ToString();  Below is my code. [Code]....
I'm trying to reference a public property from a string. How can this be done in vb.net? I have the text value of "FirstName" stored in strucParam(i).TxtPropertyName.
This is what I'm currently doing:
Dim tmpValue As String Dim ucAppName As UserControl_appName = CType(Parent.FindControl(strucParam(i).ParentFindControl), UserControl_appName) tmpValue = ucAppName.FirstName.Text
How can I use the value in strucParam(i).TxtPropertyName so that I can remove ".FirstName" from my code?
I have a page with a textbox. User enter the WCF Service URI and my program get the method names and the parameters. Then user enter the values and I want to dynamically call the method with passed parameter values.
how can I dynamically set the value of a property for a given object? For example: I have a method GetInfo(string name, Color favcolor) where name is string and favcolor is of System.Drawing.color type. How can I set the color attribute dynamically with user supplied value.
[Code]....
The last line is currently throwing an error
Object of type 'System.Drawing.Color' cannot be converted to type 'System.Drawing.Color'.
I want to do this inline in a normal HyperLink control that is not databound.
Edit: Got some good answers, but what I'm looking for is how to do this specifically in a normal HyperLink (not in a DataGrid/GridView) and inline (not via a function call or code behind).
I need to configure a property of a custom control I wrote, specifically before the control calls OnInit. If I assign it as part of the ASPX file, it naturally works, but if I instead move the assignment to different parts of the code-behind, it will throw an error for having an empty and invalid value. The following is what it looks like when functional in the ASPX page.
The property in question is FilterString, which is just a simple string. It should be noted as well that the FieldName property (inheritted from the control's base class "BaseFieldControl") would also throw an error if it is not initialized, but if I set FieldName in the code behind's OnInit method, it works correctly. FilterString is not so, it won't actually be assigned. So I know that some methods for certain properties will work for setting the property's value, but it won't always work. I tried placing it in OnPreInit as well, to no avail.
I am taking a dynamic assignment approach because the functionality of this page needs to be replicated for a number of different lists, and the FilterString and FieldName properties will differ in every case. Rather than write half a dozen mostly-identical aspx pages all with the same code behind but differing just in what those two properties are, I figured it would be wiser to use the page's query string and some derived parameters to set those properties dynamically. As such, what methods are available to accomplish this task?
I've got a SQL Server database with a table in it, which lists the file names of images. It's my intention to assign the ImageUrl of an Image control on the page, from the data in the table. I've placed a SQLDataSource control on the page, and then tried putting a FormView control there, and an Image control within that. But I don't see how I can assign the value to the ImageUrl property via data binding.
I have a UserControl that is on a masterpage... I have created the following property for the userControl in the codebehind:
[Code]....
Now I need to access this control and change that property from an aspx page that uses the masterpage with the control. I'm stuck I cannot seem to find the controls property. I can find the control and make it visible or not but I cannot find the property to modify control...
I wanted to have the Editor control without the toolbars and found this guide: [URL]
The guide shows you how to make your own class derived from the Editor class, and gives some overload functions to remove the toolbars, and only have the bold and italics button.
I made my own "customEditorSample.aspx", and was able to reproduce what was in the guide.
However, in customEditorSample.cs, when I try to access the Content property of the control, it won't show up in the intellisense.
When using the regular Editor ajax control, I can save the contents to a label by doing:
Label1.Text = Editor1.Content; and "Content" would appear in the intellisense after typing the period after Editor1.
I just started learning silverlight by creating a silverlight application in Visual Web Developer 2008. I have a public property defined in the user control. How do I access this property value in the aspx codebehind page?
