Gridview - What Property Exists To Find Out If The Grid Renders Or Not
Nov 17, 2010
When there is no DataSource assigned to my grid it doesn't render which is great!
When the datasource is empty it doesn't render - also great :-)
I am implementing some custom navigation so i want to know if there is a property that tells me if the dataview is rendered? If it is rendered i can show my custom bits otherwise i don't.
I try to run each control and then check what html did it render.
But this seems to me as an inaccurate method as whenever we add or remove the properties, or events of the control,the rendered HTML changes. Is there any book/tutorial/article to explain what is the standard HTML rendered by each asp.net control.
I have a web page, I am adding treenode value from database. I need to check if any value is already added in node then childnode value should be added in the same parent node. In vb6.0 we have something Key of the node, but here I am unable to find. Here we get only text and Value for any Node.
I have a control on a master page called "panel1". I would like to access it from my Javascript on the content page. I have tried var panel1 = document.getElementById('<%= panel1 %>'); It doesn't work since it is on the Master page.
I have a nested GridView with id grd_inner. i have to find a linkbutton in template field of grd_inner and add some attributes to it. but its giving me error.
I would like to check whether a folder exists or not if not create. I'm sure this folder exists, but for some reason I get "false" when I check with "Exists" method.
The only reason I think could be because of the W: drive? I moved this application to production site and even there it returns false.
while I'm type in Windows explorer on my localhost and on the server "W:/Webs/ASPPages/cropper/uploads" it opens this folder. So my localhost and IIS server has W: mapping.
for test I tried to create the folder then it says can't find the path...
userFolderName = @"W:/Webs/ASPPages/cropper/uploads" //I also tried @"W:WebsASPPagescropperuploads" //I also tried @"W:WebsASPPagescropperuploads" //I also tried "W:\Webs\ASPPages\cropper\uploads" DirectoryInfo dirInfo = new DirectoryInfo(userFolderName);........
I have a page where I'm using jQuery Grid. through routing I'm reaching that page and have an id being passed. eg. localhost/MyController/MyAction/5/ -- 5 being the ID passed. as I'm using jQuery Grid in the same page and to get data I'm setting url property
like this localhost/MyController/MyJQueryDataAction/ -- but for this also I need the above mentioned ID. how can I get that ID and pass it in to jQuery Grid url property on page.
Here's mt entity: Csharp Code: using System;using System.Collections.Generic;using System.Linq;namespace Venue.Domain{ using Venue.Infrastructure.Domain; public class Forum : Entity { private IList<Forum> children = new List<Forum>(); private IList<Moderator> moderators = new
[code]....
Here's my class map:
Csharp Code: using FluentNHibernate.Mapping;namespace Venue.Persistence.Mapping{ using Venue.Domain; public class ForumMap : ClassMap<Forum> { public ForumMap() { Id(x => x.Id); Map(x => x.Sequence); Map(x => x.Title);
[code]....
And here's my convention:
Csharp Code: using FluentNHibernate.Conventions;using FluentNHibernate.Conventions.Instances;namespace Venue.Persistence.Mapping.Conventions{ public class ReferenceConvention : IReferenceConvention { public void Apply(IManyToOneInstance instance) { instance.Column(instance.Property.Name + "Id"); } }}
I get the following message:Could not find a setter for property Children ...
When it gets inserted in the db the fields are blank except for volume and area so I think I have done something wrong when I'm trying to find the controls.
In my project, I need to create a user control to handle the sorting and pagination of all the grids in the application. The grid however will be different in different pages with different formatting.
I am able to do this by exposing a property from user control which takes gridview as the input.
then in page load, i bind this grid, and assign the sorting and paging event handlers to this gridview variable.
This way I am able to do the sorting and paging, but the problem is I have to bind the grid in all the post backs, and then in the sorting and paging events.
So when a user sorts, I have to bind the grid twice, once in page_load and then in sort event of user control.
I can store the first set of records in viewstate and bind that in page load, but is there any other way, so that i dont need to bind the grid in all post backs but only inside of not postback.
I have a calendar control that has a checkbox control added to each cell on dayrender. A user will check the dates that they want to add an event for and click a button that will display the modaldialog box where the user will enter the event for the selected dates. I'm having trouble looping through the calendar dates to get the checkbox contol's checked property.
I can't seem to reference a control properly, so that I could then change its properties. I have 3 fckeditor controls specified in edittemplate fields, but i only want to diplay them all if the querystring equals 1. so i created in aspx.cs file: {
I have a Sidemenu item in my ASP.NET application like below. There are two types of users in my application (Associates, Managers).When ever Associate Login then I have to disable Manager link. I am not able find visible property in codebehind since it is a HTML control. So need your support how to handle this
How would I go about displaying a databound dropdown list in a property grid, i.e. a dynamic list that can be used to set the value of an individual property?
I have created a class which inherits the HyperLinkField. I need to find the data values of the fields specified in the DataNavigateUrlFields property. I have not been able to figure out how to do this.
I have data grid with page size 15. I need to find total number of record(s) in a grid. How to do it?There is two ways to do:
1) Here I have used LINQ. So calling stored procedure again and we can done using .Count () property. But here I don't want make call to data base again.2) Creating our own logic like here I have done like:
Here two have two grid inner and outergrid, When i am click the Edit Linkbuttom i am able to see the EditItemplate of innergrid.. where i can edit the Value.. When going to update that values in Data base.. i am not able to fine the control . Here is the code
I am using a sqldatasource for filling one GridView and on page loading or before taking any action, there is no data (default value=null) and normally the datagrid is empty (using emptydatatext="no records found etc etc...").. Issue is I can not see the header of that grid in empty case, but only the emptydatatext!
I have tried to use some code of the references below, but no success, because I'm not using DataTable control as a DataSource, but directly filling the gridview from sqldatasource! useless references:

P.S. I'm not usign DataTable as a DataSource, but sqldatasource (from the Data Controls), and I want to show header, when sqldatasource is null or empty ?!
I have a page with a simple textbox, when an OrderNo is entered in te textbox the page is populated with 2 or 3 gridviews depending if the order has items reserved or on back order.
GridView1 has data about the order, like status, payment details.
GridView2 has data about orderitems, each row displays an item from the order with stock and order quantities
GridView3 has data about backorders, each row displays an item from the order with quantity reserved and quantity on back order. As is no data for GridView3 if order is not on backorder I thought that I can enclose my code inside an if block
if GridView3 isnot nothing then
'getting some data from the cells in GridView3 endif
It happened to add an extra Gridveiw Header in row_databound event , It did worked fine on !Postback but disappered on Page.Postback . Quick google search guided me to move the event to Row_Created event and every thing is okay .
Can any expert post some pointers , differnces between grid row_created vs row_databount with some sample table data created dynamically behaviour of both the events in !Postback and page.Postback .
