new to this forum, and visual studio web development. Here is what I want to do: -From a webpage on my website, I would like to upload multiple photos to an sql database, but instead of having a container or field name for each photo, i would like to have multiple photos on one field, on each record.Then, I would like to display it back one record at a time, but with the capability of displaying all the pics from the one field holding the pics. Similar to the function in MS Access, where I can upload mutiple photos in one field and then display them back by just scrolling through them on the same record.
I have few textboxes and I want to search the text (partial search is also required) in the database and then show the result in a telerik grid. The grid has to be hidden initially and when I click the search button it should show up and display the results.
Scenario: I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.
My requirement is: I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.
Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.
I am trying to bind a DataTable into a ObjectDataSource. This ObjectDataSource data will be used to bind into my LocalReport in ReportViewer. I have already successfully binded my data into the DataTable. My problem now is how do i bind the data in my DataTable into the ObjectDataSource so that it can be used in my report?
I am using a dropdown list in gridview and populating it from database.However ,i am getting "object reference not set to an instance ..." error even though i have reference.I have two more similar drop down list and they are working perfectly.
I am uploading the options for the dropdownlist from a "tab delimited" text file for all the dropdown list.I am not getting where exactly the problem is.
I have a Dropdownlist in an itemTemplate in a gridview. My gridView binds to dataTable1 (from which the selected value for dropdown comes from) and dropDown binds to dataTable2 (i need to get DataValueField and DataTextField from here).
Im struggling with a way to bind multiple rows of sql data to specific controls, what im trying to acheive is having a list of questions / answers in my SQL db and loading them into my web form to build a questionaire.
The data i load into the form depends on criteria like which questionaire is it (there will be 2 seperate ones) and what language should it be loaded in, this will be controlled using drop down lists and passing these parameters to the SQL select statement.
The problem i have is i am unsure which method to pull the data out of the question column in my table, and bind it to seperate controls row by row, should i use a SQLDataReader or load the data into a dataset, or run a stored procedure to pull the data?
Which is the best way to get data from sql and bind it to controls in this situation?
I'm trying to implement a recipe search page that allows users to specify search criteria by selecting checkboxes that match desired recipe attributes. All the data is stored in a database uing tables with 1 - many relationships. Each recipe can have multiple attributes from any of 5 attribute tables. I want to find all the recipes that match the user-selected criteria and display them in a grid. For example, the user may want a breakfast (attribute 1) recipe that is made with fruit and milk (attributes 2 and 3), is low-fat and high fiber (attributes 4 and 5), and takes less than 15 minutes to prepare (attribute 6). The query for this example might look something like:
FROM recipes, recipeMeals, recipeDishes, recipeFoodGrps, recipeNutrients, recipeFixTimes
WHERE recipes.id = recipeMeals.recipeId and recipes.id = recipeDishes.recipeId and recipes.id = recipeFoodGrps.recipeId and recipes.id = recipeNutrients.recipeId and recipes.id = recipeFixTimes.recipeId and recipeMeals.mealId in (1) and recipeDishes.dishId in (5) and recipeFoodGrps.fdGrpId in (1, 6) and recipeNutrients.nutrAttsId in (2, 3) and recipeFixTimes.fixTimeId in (1)
I' can generate the SQL but can't figure out how to bind it to a grid control. No could I see how to get any of the data controls to build the query for me. Is there a way to say "execute this query and display the results in a GridView"?
I have a SQL table with questions and store the answers. Depend on the user selections, I need to display dynamically the questions and try to get the answers for them. ie: sometime I need to display 3 questions, and get 3 answers; sometime 5 questions, and try to get 5 answers.I know about dynamically loading the questions and display them. But how do I dynamically binding some kind of data control to get the dynamic answers back?Normally, in .aspx I would have <asp:TextBox ID=MyAnswer ....> or <DropDownList ID=MyDropDownList....> then I would use the C# behind to refered to MyAnswer.Text or MyDropDownList.SelectItem.....But in the dynamicly generated forms, how do generate multiple questions and bind somekind of multiple "TextBox" with ID and be able to refer them from the c# behind?
I'm using VS2008. When a dataset is bound to the DataSource of a ListView, SelectedIndexChanged event does not fire. If I used DataSourceID instead, it has no problem. But SelectedIndexChanging event fires for both.
why and how I can get SelectedIndexChanged event fired when DataSource is used?
I am trying to bind the datasource of a ddl which is located inside the EditTemplate of a TemplateField.When is the best time to bind this datasource (after loading grid, before editing, ? (Note: I must do this in code behind).I am currently trying to bind it on the edit command:
[Code]....
The issue is that the list retrieved from the LoadLists method is null when passing to the LoadList method where the datasource is bound.
I have a datasource (quite heavy to run) and a Gridview on the page.
By default when the page is loaded the datasource and Gridview bind and display. However since the datasource is heavy I want on page load these 2 will not bind.
I want them to bind only on a button click. How to stop the datasource and Gridview from binding on 1st page load ?
